Which has the highest pH ?

$\mathrm{NH}_4 \mathrm{Cl}$ solution is acidic, its $\mathrm{pH} < 7 . \mathrm{NaNO}_3$ solution is neutral, its $\mathrm{pH}=7 . \mathrm{CH}_3 \mathrm{COOK}$ and $\mathrm{Na}_2 \mathrm{CO}_3$ solutions are basic their $\mathrm{pH}>7$. But $\mathrm{Na}_2 \mathrm{CO}_3$ solution is more basic, its $\mathrm{pH}>\mathrm{pH}$ of $\mathrm{CH}_3 \mathrm{COOK}$ solution.
