Five solutions A,

Answer :

(a) (i) The pH of neutral solution is 7. Thus, the neutral solution is D with pH=7.

(ii) The pH value of greater than 7 indicates the basic solution. Higher pH value represents strong alkaline solution. Thus, strong alkaline solution is C with pH=11.


(iii) The pH value of less than 7 indicates the acidic solution. Lower pH value represents a strong acidic solution. Thus, a strong acidic solution is B with pH=1.


(iv) weakly acidic: A (pH=4);


(v) weakly alkaline: E (pH=9)


(b) pH scale quantifies the concentration of hydrogen ion in a solution. The pH value increases with a decrease in hydrogen ion concentration. The solution having pH 11 will have the minimum hydrogen ion concentration than the solution having pH 1. Thus, the arrangement of solutions in the increasing order of their hydrogen ion concentrations as follows:


C < E <D <A <B
(pH 11) < (pH 9) <(pH 7)< (pH 4)< (pH 1)
