What is pH Measurement and Buffer Solutions about?
This document describes an experiment to measure pH and demonstrate buffer capacity. The objectives are to measure pH using pH paper and to differentiate pH changes in buffered versus unbuffered solutions. Procedures are outlined to prepare buffer solutions from sodium acetate and acetic acid, measure the initial pH, and add single drops of HCl or NaOH while monitoring pH changes. Separate procedures add acid or base individually to unbuffered water and record pH after each addition to show larger pH shifts
