CHM110H5 Study Guide - Final Guide: Titration Curve, Ph Meter, Titration
Document Summary
The purpose is to identify an unknown acid by using ph indicators and titrating it with a base to obtain the ka value using the equation: The concentrations for this equation would be identified by ph titration and the resulting ka value would be compared to those of identified acids to see which acid the ka value is the same as. A known acid, hcl, is also to be titrated with a strong base to find the concentration of it at the equivalence point. The ph meter was placed in each of three buffer solutions with known ph values. In between placing the meter in the solutions, the meter was rinsed with distilled water. The unknown acid was placed in a beaker and titrated with sodium hydroxide. A magnetic stirring bar kept the solution mixed. Moderate amounts of naoh were titrated until a large increase in ph occurred.
