Question

Select the correct statement regarding salt solution of week acid and strong base.​

Answer 1

Answer:

(A) Salt with strong acid and strong base completely dissociates into ions. These ions do not react with hydrogen ions and hydroxide ions. The concentration of hydrogen ion ions and hydroxide ions in water remains the same. Hence, salt with strong acid and strong base forms neutral solution as there is no hydrolysis.

(B) Ammonium acetate is a salt of weak acid acetic acid and weak base ammonium hydroxide. After hydrolysis, acetic acid and ammonium hydroxide are obtained. They have equal relative strengths. Hence they produce an equal number of hydrogen ions and hydroxide ions. Therefore, the solution is neutral with pH 7.

(C) NH

4

HSO

4

is a salt of a strong acid (sulfuric acid) and a weak base (ammonia). On hydrolysis, the number of hydrogen ions produced is greater than the number of hydroxide ions. Hence, the solution is acidic in nature.
