WebEnough 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. WebTherefore, the new pH of the buffer after adding 1.0 mL of 2.00 M HCl is 4.85. ♦ To calculate the new pH after adding 1.0 mL of 2.00 M NaOH to a fresh 50 mL of the buffer, we can use a similar approach. The NaOH reacts with the acetic acid (CH3COOH) in the buffer to form acetate ion (CH3COO-) and water (H2O): CH3COOH + NaOH → CH3COO- + H2O
