Choose the correct statement:

Options

A. `pH` of acidic buffer solution decrease if more salt is added
B. `pH` of acidic solution increases if more salt is added.
C. `pH` of basic buffer increase if more salt is added.
D. `pH` of basic buffer increase if more salt is added.

Answer

B, C

Explanation

Acidic buffer: `pH = pK_(a) +"log"(["Salt"])/(["Acid"])` If more salt is added, `pH` increases.
Basic buffer: `pOH = pK_(b) +"log"(["Salt"])/(["Base"])` If more salt is added, `pOH` increases or `pH` decreases.
