Enough water is added to the buffer in Question 30 to make the total volume 10.0 L. Calculate

(a) the pH of the buffer.

(b) the pH of the buffer after the addition of 0.0300 mol of HCl to 0.710 L of diluted buffer.

(c) the pH of the buffer after the addition of 0.0300 mol of NaOH to 0.710 L of diluted buffer.

(d) Compare your answers to Question 30(a)–(c) with your answers to (a)–(c) in this problem.

(e) Comment on the effect of dilution on the pH of a buffer and on its buffer capacity.

Reference Question 30:

A buffer is made up of 355 mL each of 0.200 M NaHCO₃ and 0.134 M Na₂CO₃. Assuming that volumes are additive, calculate

(a) the pH of the buffer.

(b) the pH of the buffer after the addition of 0.0300 mol of HCl to 0.710 L of buffer.

(c) the pH of the buffer after the addition of 0.0300 mol of KOH to 0.710 L of buffer.
