Question

Create a new column and calculate the new rate of change between each pair of points. Put the first computed value into cell C4. What observations can you make of your rate of change results? 

Titration is a method of chemical analysis in which a reactive substance is slowly added to another substance, and some property of the combined substance is measured. This procedure is taught in CHM 116, General Chemistry II. We will be looking at an example of acid-base titration. Specifically, 25 mL of an unknown monoprotic weak acid is titrated against 0.105M NaOH (which is a strong base). This means we are adding the base to the acid using a burette in a slow and precisely controlled manner. We measure the pH after each addition. (A pH of less than 7 is an acid, and a pH of more than 7 is a base.)
