1.	Which of the following statement (s) is/are correctA. pOH of an acidic buffer decreases if less salt is addedB. pOH of a basic buffer decreases if less salt is addedC. At the saturation point the ionic product is equal to solubility productD. The term solubility product is only for sparingly soluble salt
Answer» Correct Answer - A::B::C `pH = pK_(a) + log.(["Salt"])/(["Acid"]), pOH = pK_(b) + log.(["Salt"])/(["Base"])` Thus as salt concentration decreases for acidic buffers, so pH decreases. Statement (a) is correct, Thus as salt concentration decreases for basic buffers, pOH decreases, Choice (b) is correct. For any salt when `Q = K_(sp)` Hence the solutions is saturated. Hence choice (c) is correct. The solubility product is for all salts, choice (d) is incorrect.
