Experiment #: 3 
Title: Titrations and titration curves 
Purpose: The purpose of this to perform titration analyses, including neutralization titrations, 
which occur between an acid and a base. 
Procedure: 
After gathering the necessary supplies, it was decided that we would perform reactions between 
the following solutions: strong acid/strong base, weak acid/strong base and strong acid/weak 
base. 
Standardization titration of NaOH: Used a strong acid/weak base. We determine the molarity 
of ...

Title: Buffers 
Purpose: The purpose of this lab is to determine how buffers affect the pH of a solution in order 
to observe how a buffer is resistant to pH changes. Additionally, we determined how enzymes 
activity is affected by pH. 
Procedure: 
Part 1: Determine pH of sodium acetate in water & buffer 
1. 2 pH electrodes are place in 2 separate beakers, one filled with tap water & one is filled 
with a pH 7 buffer (both have an approximate pH of 7)
