Chemistry - Ionic Equilibrium Question with Solution | TestHub

Pure water is neutral in nature, $[{\mathrm{H}}^{+}]=[{\mathrm{OH}}^{-}]$. When this condition is disturbed by changing the concentration of ${\mathrm{H}}^{+}$ or ${\mathrm{OH}}^{-}$, the neutral solution changes to acidic $\{[{\mathrm{H}}^{+}]>[{\mathrm{OH}}^{-}]\}$ or basic $\{[{\mathrm{H}}^{+}]<[{\mathrm{OH}}^{-}]\}$. This change occurs during salt hydrolysis.

When 50 ml of 0.1 M NH₃ is added to 50 ml of 0.05 M HCl solution, the pH is nearly
