Lecture

Buffer Solutions: pH Calculations

Description

This lecture covers the preparation of buffer solutions and the calculation of their pH using the equilibrium constant Ka. It explains the relationship between pH, pKa, and the degree of dissociation of acids in water. The concept of molarity is introduced, along with examples of calculating molarity for different substances. The lecture also demonstrates how adding a strong base affects the pH of a buffer solution. Dilution calculations and the use of stock solutions in reactions are discussed, emphasizing the importance of maintaining desired concentrations.
