A) Neutral
B) Basic
C) Unaffected
D) More acidic
Correct Answer: A
Solution :
\[pH=5,\] means \[[{{H}^{+}}]={{10}^{-5}}M.\] After dilution \[[{{H}^{+}}]={{10}^{-5}}/100={{10}^{-7}}M\] \[[{{H}^{+}}]\] from \[{{H}_{2}}O\] cannot be neglected. Total \[[{{H}^{+}}]={{10}^{-7}}+{{10}^{-7}}=2\times {{10}^{-7}}\] \[pH=7-0.3010=6.6990=7\](neutral).You need to login to perform this action.
