💡 Solution & Explanation

The pH of an acidic buffer is largely independent of volume upon moderate dilution because the ratio $[\text{Salt}]/[\text{Acid}]$ remains constant. Therefore, its pH does not "always increase" (Statement I is false). For a simple aqueous acid, dilution lowers the $[\text{H}^+]$ toward the neutral $10^{-7}\text{ M}$, thereby always increasing its pH toward 7 (Statement II is true).
