Question
Consider two buffer solutions, Buffer A and Burrer B, described below. Note that this question contains two parts. The molar mass of NaC2H3O2 is 82.04 g/mol. Buffer A: contains 12.3 g of sodium acetate, NaC2H3O2, dissolved in 500.0 mL of 0.200 M ace- tic acid, HC2H3O2. Buffer B: contains 1.23 g of sodium acetate, NaC2H3O2, dissolved in 500.0 mL of 0.0200 M ace- tic acid, HC2H;O2. a) Calculate the pH of each buffer. Ka of acetic acid 1.8×10-5 b) Which buffer has the higher buffer capacity? How do you know?
