Experiment 1

Lab Techniques and Measurements

Purpose: The purpose of this lab experiment is to review and learn the proper techniques for the measurement of length, mass and temperature. After this experiment I expect to have a better knowledge on how to correctly and efficiently measure for future lab experiments.

Data:
DATA TABLE #1

DATA TABLE#2-

DATA TABLE#3-

DATA TABLE #4

DATA TABLE #5

DATA TABLE #6

DATA TABLE #7

DATA TABLE #8

Data Table #9

Observation- While performing the lab experiments in the first unit, my observation included finding the appropriate tools in the kit in order to carry out the tasks. These experiments really showed me how to differentiate the types of tools we are using and understand the differences and reason for the differences in each. Touch was a big activated sense in these experiments, the heat from boiling the water and the cold ice from the temperature labs allowed for the connection between the results and the way the temperature felt.
Conclusion-
After performing each lab I have a much better understanding on what is expected and how to carry our future labs. I learned measuring techniques and although there is much room for improvement on my part, I think I have a good sense of what to expect and how to appropriately calculate my experimentations. The lab that I struggled with the most was the one represented in Table 9. I found the calculation of molarity to be a little confusing. I had a hard time producing results on this particular lab. I continued to redo it in attempt to get the correct calculations. I hope that I can take with me into future lab assignments the tools and know how to produce successful labs and results.
Questions-
A. Water boils at 100°C at sea level. If the water in this experiment did not boil at 100°C, what could be the reason?
- The reason

    The identification of the melting point of the organic acid was done to find another characteristic of the acid and to test the purity of the recrystallized pure acid. A 2-4 mm layer of unknown sample was placed into a capillary tube sealed on one end. Then the capillary tube was inserted into the side a Bibby Sterlin device. The plateau was set to 200°C on the melting point apparatus. Once the plateau temperature was reached, the sample was watched carefully. When the sample first began to melt and when it was fully melted was recorded. These numbers were the range of the melting point. A slow melting point of the unknown organic acid and a standard sample was completed next. A new plateau was set about 10°C lower than the observed melting point of the unknown sample. This time once the plateau was reached, the heating was no more than 1°C per minute. This gave a much more accurate read of both melting points. If the standard did not melt in the range listed on the label of the bottle, that meant the machine was not working properly. The standard sample and the unknown organic acid melted in their appropriate ranges.…

    2. In 1963 a student named Erasto B Mpemba noticed that placing recently a recently boiled mixture of milk and sugar into the refrigerator it froze into ice-cream faster than another students mixture that was not heated. He asked his physics instructor why this had happened and his physics instructor informed him “you are confused, that cannot happen” this response highlights the need for objectivity in scientific studies. After repeatedly asking various instructors to explain his observations Mpemba took two 50ml beakers and filled one with water from the tap and one from hot water from a boiler and put them into a freezer, after an hour he discovered that their was in fact more ice formation in the sample from the boiler. Dr Osborne visited the school where Mpemba studied and…

    Writing reports in organic chemistry lab may differ from the way it’s done in general chemistry. One goal of this course is to introduce you to the record keeping methods used in research labs. Such methods are designed to organize experimental data in a format similar to that required for publication in major scientific journals. Here are some important considerations that apply in research settings. 1. Your work is unique, meaning that you might be the only person performing certain experiments. 2. Research is an ongoing process. The projects assigned to you will likely continue after you leave. People assigned to those projects will need to access your records for reference, or to attempt to reproduce work you did. Permanence is a characteristic of properly kept research records. 3. It is therefore important to follow guidelines for clear writing. In addition to writing legibly, you should use permanent ink. A ballpoint pen is adequate for this purpose, but a pencil is obviously not. 4. Write your records by hand, either while conducting the experiment, or immediately afterwards. This is important to avoid forgetting important details. You will make mistakes, but that is less important than recording data while it’s still fresh in your mind. 5. Mistakes are not to be erased. A “mistake” might turn out to be important information later. You and others must be able to read what you wrote. If you make a mistake, draw a line across the text, but make sure it remains legible, like this. 6. Remember: your lab notebook is the first line of documentation that exists of your experiments. It is important that this information be as fresh and accurate as possible. Don’t worry if it’s imperfect. You will have occasion to produce a formal, well written report later. It may be a thesis or a scientific publication, but it will likely bring together several experiments with a…

    In our second part of our experiment to determine the molarity of NaOH, we rinsed a burette with about 5ml of water and another 5ml of NaOH to prepare it for the experiment. We then measured exactly 25ml of the prepared KHP from the previous part into a 250ml Erlenmeyer flask and added 2 drops of the indicator, phenolphthalein. Next we filled the burette with the approximately 0.1 M NaOH so that our initial volume will be 0.0mls. We then started our titration by carefully pouring a little amount of the base into the prepared 25ml of KHP with phenolphthalein until we reached the end point. Since the molarity of the NaOH was designed to be more or less the same with the acid, we knew that it would take equal amount of the base to reach the endpoint. Thus we added the first 20 mls in about 5ml increment and swirled to mix after each addition then added just 6-7 drops for the next mls. After we started observing a pink color, we started adding just 2 drops at a time and swirl the flask. When we…

    Lab Reports

    • 750 Words
    • 3 Pages

    Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab, we sometimes can observe only the physical part of the experiment, or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However, in order to understand and achieve more from just simply doing the experiment, we write lab report to more profoundly understand the internal meanings of the experiment we do, and the eventual purpose of the lab. Doing a lab report are also essential to making corrections for further experiments similar to previously done ones. Pass experiences can help improve and better the new lab in many ways such as the procedure. We can make the procedure clearer and more precise. By doing so, we can do our best to limit the possibility of ingredients that may alternate final results popping up during a lab. Without a precise data and purpose, a lab would not be a lab because it has no means of proving anything that we don’t know of. Too many alternating factors always cause a lab to be useless because we cannot focus on the specific thing we are looking at. Thus, a lab report is essential not just for the lab that the report is for, but essential for bettering future similar experiences.…

    An acid-base titration is a procedure used in quantitative chemical analysis to determine the concentration of either an acid or a base. Titration is the slow addition of an acid (or a base) of known concentration from a burette (a narrow graduated cylinder) to a base (or an acid) of unknown concentration fin an Erlenmeyer flask. There are two types of acids: strong acid and weak acid, and also two types of bases: strong base and weak base. Therefore four types of acid-base titrations are possible: strong acid-strong base, strong base-weak acid, weak acid-strong base and strong acid-weak base titrations.…
