Question

At a certain temperature, the value of pKw is 13.4 and the measured pH of a solution is 7. The solution is (A) acidic (B) basic (C) neutral (D) unpredictable

Tardigrade Admin · Accepted Answer

At this temperature pH of neutral solution will be 13.4/2 i.e. 6.1. Thus, pH greater than 6.7 at this temperature refers to basic solution

Q. At a certain temperature, the value of $p K_{w}$ is 13.4 and the measured pH of a solution is 7. The solution is

acidic

basic

neutral

unpredictable

At this temperature $p H$ of neutral solution will be $13.4/2$ i.e. $6.1$ . Thus, $p H$ greater than $6.7$ at this temperature refers to basic solution
