A) Acid A is 10 times stronger than acids B
B) Strength of acid A: strength a of acid \[B=4:5\]
C) The strengths of the two acids can not be compared
D) Acid B is 10 times stronger than acid A
Correct Answer: A
Solution :
\[p{{K}_{a}}\] of acid \[A=4\] ; \[p{{K}_{a}}\]of acid \[B=5\] We know that \[p{{K}_{a}}=-\log \,\,{{K}_{a}}\] \ Acid A \[{{K}_{a}}={{10}^{-4}}\] Acid B \[{{K}_{a}}={{10}^{-5}}\] Hence A is ten times stronger than that of B.You need to login to perform this action.
