Enough water is added to the buffer in Question 29 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 0.0500 mol of HCl to 0.600 L of diluted buffer.

(c) the pH of the buffer after the addition of 0.0500 mol of NaOH to 0.600 L of diluted buffer.

(d) Compare your answers to Question 29(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 29:

A buffer is made up of 0.300 L each of 0.500 M KH₂PO₄ and 0.317 M K₂HPO₄. Assuming that volumes are additive, calculate

(a) the pH of the buffer.

(b) the pH of the buffer after the addition of 0.0500 mol of HCl to 0.600 L of buffer.

(c) the pH of the buffer after the addition of 0.0500 mol of NaOH to 0.600 L of buffer.
