Characteristics of a buffered solution laboratory questions 1. write a balanced equation for the dissociation equilbrium of acetic acid. 2. in activity 2, there was 2 ml of buffer per well. calculate the final ph of the undiluted buffer after 0.25 ml of 0.1 m naoh are added. the ka of ch3cooh = 1.8 x 10-5. use the ch3cooh buffer concentration calculated in data table 2, a balanced ch3cooh +naoh reaction equation, an ice table, and a balanced dissociation equilibrium equation to determine your ph. 3. what is the final ph of the second dilution after adding 1 drop of 0.1 m naoh
