Titration of a Diprotic Acid
The goal of this lab was to identify the unknown diprotic acid by finding its molecular weight.
0.1 NaOH was titrated into the diprotic acid solution, and equivalence points on a titrati
The purpose of this lab was to determine the buffer capacity of two different acid-base buffer
solutions. Two different buffer solutions were prepared using different amounts of sodium acetate and
