Answer:
ANSWER
(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 (OH
−
) 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.
