About this document

pH Changes in Phosphate Buffer Solutions by Karren Reyes is a document available to read on EtoBox.

This document summarizes three key points about buffers: 1. A phosphate buffer was prepared using NaH2PO4 and Na2HPO4, and upon dilution its pH slightly increased due to changes in ionic strength and pKa. 2. Titration of solutions with concentration ratios of 10:100 and 1:100 with NaOH required different volumes as expected, with more NaOH needed for the 10:100 solution. 3. Buffering capacity is determined by conjugate acid and base concentrations, so diluting a buffer decreases its ability to resist
