Answer
$HCl$, $NH_4Cl$, $KNO_3$, $KCN$, $KOH$
Work Step by Step
1. Since the concentratrion is the same, we just have to identify the strength of the compounds.
** Remember, conjugate pairs of strong acids and bases are insignificant electrolytes.
- Determine the significant electrolytes in each compound:
- $KOH$ is a strong base.
$K^+$: Insignificant acid.
$N{O_3}^-$: Insignificant base.
-$KNO_3:$ Neutral
$K^+$: Insignificant acid.
$CN^-$: Weak base.
- $KCN$: Low basicity.
$N{H_4}^+$: Weak acid
$Cl^-$: Insignificant base.
- $NH_4Cl$: Low acidity.
- $HCl$: Strong acid.
2. In order of most acidic to most basic:
$HCl, NH_4Cl, KNO_3, KCN, KOH$
