A) acidic solution of \[{{H}_{2}}S{{O}_{4}}\]
B) alkaline solution
C) acidic solution of \[HCl\]
D) neutral solution
Correct Answer: A
Solution :
\[{{K}_{2}}(S{{O}_{4}}).A{{l}_{2}}{{(S{{O}_{4}})}_{3}}.24{{H}_{2}}O\] \[{{K}_{2}}S{{O}_{4}}+A{{l}_{2}}{{(S{{O}_{4}})}_{3}}+24{{H}_{2}}O.\] \[A{{l}_{2}}{{(S{{O}_{4}})}_{3}}\] undergoes hydrolysis to give\[{{\text{H}}_{\text{2}}}\text{S}{{\text{O}}_{\text{4}}}\] due to which aqueous solution of potash alum is acidic.You need to login to perform this action.
