The following 0.1 M aqueous solutions are arranged in order of increasing pH, with the highest pH on the far right.

\begin{array} { | l | l | l | l | l | } \hline \mathrm { C } _ { 5 } \mathrm { H } _ { 5 } \mathrm { NHCl } & \mathrm { HClO } & \mathrm { KNO } _ { 3 } & \mathrm { NaClO } & \\\hline\end{array}

Which one of the following 0.10 M aqueous solutions should be placed in the empty box?

Quizplus · Accepted Answer

NaCN is a salt that comes from a strong base (NaOH) and a weak acid (HCN), making its solution basic. When placed in order of increasing pH, a basic solution would have a higher pH than the neutral solution (KNO3) and the weak base solution (NaClO), fitting the criteria for the empty box on the far right.
