Buffers - Study guides, Class notes & Summaries

Experiment #: 5 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) 2. A scoop of sodium aceta...
