Ammonia and Hydrochloric Acid Lab
Chemistry 1

Abstract
The straw should be cut shorter to 8 cm in order to make the solid ring appear in the center of the straw. We achieved our goal, cutting the straw caused the gases to not have to go as far, and meet in the middle.

Background
The particles in a gas are very loose and tend to move around a lot very quickly. The particles in a solid are very compact and vibrate but don’t really move very much. The particles in a liquid however are more lose than the particles in a solid but not less than a gas.
Materials
Goggles | Apron | Gloves | Straw(1) | Ammonia | Hydrochloric acid | Q-tip(2) | Test tubes | Hood | Pencil | Paper | pipette | Tape | | |
The two hazardous materials being used are Ammonia and Hydrochloric acid. Goggles, aprons, and gloves are used for protection for eyes, skin, and clothing against the chemicals in this lab.
Procedures
1. Put on goggles, apron, and gloves. 2. Find all materials for experiment (Ammonia, Hydrochloric acid, test tubes, Q-tips, ect.) 3. Put straw on top of tape to secure it. 4. Open Ammonia under the hood. 5. Take Q-tip and dip it into the ammonia 6. Open Hydrochloric acid under the hood 7. Take Q-tip and dip it into the hydrochloric acid 8. Place one Q-tip on one end of the test tube and the other Q-tip on the other end 9. Making sure the straw is stable, insert one Q-tip into one side of the straw and the other Q-tip into the other side. 10. A ring should appear, document what you see.
Observations

control experiment
Our group will be manipulating the length of the straw in order to move the ring to the center.

Data
The straw was cut to 8 cm long. It was about 3 cm from the ring to each Q-tip.
Analysis
a)Where did the solid (ring) come from? What would you consider to be the reactants?
-The solid ring came from the chemical reaction between the ammonia and the hydrochloric acid. The chemicals

    Acids, Bases, and pH Lab In this lab the testing of whether or not a substance was an acid or a base occurred. Each substance was tested with the indicators red litmus paper, blue litmus paper, pH paper, phenolthalein, bromthymol blue, and phenol red. While the substances were tested the group noticed that the substances tested with the red and blue litmus paper, the phenolthatein, bronthmol blue were the easiest to interpret. The color changes that occurred when this indicator was put into a substance…

    Amino acids are important building blocks; they play an essential role in the formation of proteins and as intermediates in metabolism. Amino acids can serve as cell signaling molecules and can regulate gene expression. An optimal amount of amino acids is essential for health. There are over 500 amino acids, however only 20 are commonly found. Amino acids all have an amine functional group and a carboxylic acid functional group. They differentiate from each other in their side chains. Only 10 of…

    Anna Powell 2nd I.Title: Acid-Base Titrations AP Chemistry Laboratory #6 II.Purpose: The purpose of this experiment is to standardize a sodium hydroxide solution and use the standard solution to titrate an unknown solid acid. The equivalent mass of the solid acid will be determined from the volume of sodium hydroxide added at the equivalence point. The equilibrium constant, Ks, of the solid acid will be calculated from the titration curve obtained by plotting the pH of the solution versus…

    Experiment #5: Acid Burn!!! Introduction The goal of this lab was to correctly prepare a 0.2M solution of NaOH, identify highly acidic household cleaning chemicals, and determine their concentration (molarity) through titrations using the previously prepared 0.2M NaOH solution. Experimental First, to create 0.5L of 0.2M solution of NaOH, standard 3M NaOH solution was obtained. Next, calculations were performed to determine the amount 3M NaOH necessary to create 0.5L of the 0.2M solution and, as…

    The purpose of this experiment was to study the effect acid rain has on seed germination and after performing this experiment is can be concluded that acid rain has a negative effect on seed germination. When seeds are soaked in an acidic solution the process of germination slows. Acidic solutions, while do slow growth of a seed, they do not kill the seed. A seed can be dormant for a majority of its lifespan, seeds watered with acid solutions stayed in a dormant condition. For example, trial three…

    (Fe3+ ) form. Ferric form is not usually absorbed in the body. In the stomach, there is low pH of 2 due to presence of gastric acids such as Hydrochloric and Ascorbic acids. These acids provide an acidic environment for reduction of ferric iron to ferrous (Fe2+). Ferrous iron can be absorbed in the body system. As in following equation of iron (iii) reaction with Ascorbic acid , the product is iron (ii) chloride which is soluble 2 Fe3+ (s) + C6 H8 O6 (aq) → 2 Fe2+ (aq) + C6 H6 O6 (aq) + 2 H (aq)+…

    Introduction: In this lab, we measured the acid-base strengths of seven separate organic compounds. The lab was painless to perform, it consisted of adding a small amount of one of the organic compounds to a well, and testing the pH via testing paper. The color of the paper was then analyzed to determine what the pH of the compound was. The structures were benzenesulfonic acid, benzoic acid, benzyl alcohol, benzylamine, p-cresol, and p-toluidine. My initial hypothesis about the acidity/basicity…
