When 110 mL of 0.12 M NaF is added to 110 mL of 0.12 M HF,relative to the pH of the 0.10 M HF solution the pH of the resulting solution will
A)become 7.
B)decrease.
C)increase.
D)remain the same.

Quizplus · Accepted Answer

When NaF is added to HF, a neutralization reaction occurs, resulting in the formation of HF and F- ions. This reaction shifts the equilibrium towards the formation of F- ions, which are basic in nature. Therefore, the pH of the resulting solution will increase from the pH of the 0.10 M HF solution.
