    MEASURING pH Date of Lab: 02/09/13 Date Report submitted: 02/26/13 Purpose of the experiment By doing this experiment‚ we were trying to learn how to measure a pH with a pH meter to determine whether a solution is weakly‚ moderately or strongly acidic or basic; but also to compare the different data founded to see how the addition of certain liquid to a solution may affect the pH of the initial solution. Materials We used: * Tap water‚ distilled water‚ Soda and milk as the main

  • Ph Scale

    The pH Scale is a scale made to show how acidic or alkaline a substance is. The pH of something is measured with pH paper which can vary from wide range paper‚ which covers all ph’s‚ but is not as accurate at some others. There are pH papers that get very specific that can have a range such as 2 or 3 and get much more precise. The neutral on the scale is 7. Anything that is below 7 is considered acidic and anything above 7 is considered alkaline. Acidic substances contain more H+ than OH-. H+

    Acids‚ Bases‚ and Buffers Introduction: The pH scale is used to determine how acidic or basic a solution is‚ ranging from 1-14. The most acidic of all acids are at a pH level of 1 and the most basic of all bases are at 14. The neutral pH level is 7‚ which is what drinking water is. The pH level is determined by the amount of H+ ions present in a solution‚ and the more H+ ions there are the more acidic it is‚ and the lack of these ions results in more basic solutions. One distinguishing feature

    Cesar Bizarroque Wesam Daker Bio 1107k-11 10/25/14 How pH levels impact tyrosinase activity Abstract: The purpose of our research utilizing the different pH levels was to test how a specific pH level would impact tyrosinase activity. First we added 4.0 mL of pH in each corresponding test tube and then added 0.5 mL of substrate (catechol) into each test tube. In the instructions it says to apply your 0.5 mL of tyrosinase (potato extract) as well but you have to blank the spectrophotometer before

  • pH and its meaning

    pH pH means Power of Hydrogen or Potential of Hydrogen. pH is a scale of acidity from 0 to 14. It tells how acidic or alkaline a substance is. More acidic solutions have lower pH. More alkaline solutions have higher pH. Substances which are not acidic or alkaline i.e neutral usually have a pH of around 7. Acids have a pH less than 7. Alkalis have a pH greater than 7. There are a lot of ways for finding the pH of something. One way is to use litmus paper. The pH paper is able to tell how strong

    Lab Report: Purpose: The Objective of this lab was to learn how to measure the pH (or acidity) of commonly known fluids‚ using the correct tools and procedures. To then use that data to document the changes noticed when mixing those same fluids and changing their respective pH levels. Materials: In order to conduct this experiment several pieces of equipment and other materials were needed. The first item was a graduated cylinder‚ which was used in order to measure out the precise

    Question 1 Critique Dr. Honeydew’s report. Specifically‚ discuss what is missing and how the missing information should have been presented. First the PH measurements‚ Dr. honey dew does not explain how the PH device was calibrated or if the blood sample was added or mixed with anything prior to the measuring of the pH (like water‚ etc.). In regards to the absorption spectroscopy‚ the method by which the concentration was obtained is questionable. Was the concentration known before the experiment

    Effects of Temperature and pH on Enzyme Function Chelsie Mesa Section 0479 Robin Cotter Introduction The purpose of this experiment is to identify three unknown enzymes. This is done by using different temperature and pH to affect the function of the enzyme‚ which ultimately‚ will affect how much maltose is produced. Enzymes are proteins that help catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process are called substrates‚ and the enzyme
