Assertion (A): `pH` of water increases with an increase in temperature. Reason (R) : `K_(w)` or water increases with increase in temperature.A. If both (A) and (R) are correc, and (R) is the correct explanation of (A).B. If both (A) and (R) are correct but (R) is not the correct explanation of (A).C. If (A) is correct, but (R) is incorrect.D. If (A) is incorrect, but (R) is correct. |

Answer» Correct Answer - D `(A)` is wrong . Dissociation of water is an endothermic reaction, so increasing `T` will increase `[H^(o+)]` and hence decreases in `pH. (R)` is correct. |
