Question

What effect does the concentration of $H^{+}$ ions have on the nature of the solution?
Do basic solutions also have $H^{+}\left(aq\right)$ ions? If yes. then why are these basic?
Under what soil condition do you think a farmer would treat the soil of his farm with quicklime.

Answer 1

(a) The concentration of $H^{+}$ (aq) ions determines the acidic nature of the solution. Hence, the acidity of a solution increases with increases in the concentration of $H^{+}$(aq) ions and vice versa.

(b) Yes, basic solutions also have $H^{+}$(aq) ions. They are basic because the concentration of hydroxide ($O{H}^{-}$) is more than the $H^{+}$(aq) ions.

(c) If the soil is acidic then it should be treated with quicklime or slaked lime to make it neutralize so that soil can be made proper for cultivation.
