A) 6.0
B) 8.0
C) 6.95
D) 9.5
Correct Answer: C
Solution :
\[{{10}^{-6}}\,M\,HCl={{10}^{-8}}M\,[{{H}^{+}}]\]. Also from \[{{H}_{2}}O\] \[[{{H}^{+}}]={{10}^{-7}}M\] Total \[[{{H}^{+}}]={{10}^{-7}}+{{10}^{-8}}={{10}^{-7}}[1+0.1]\]\[={{10}^{-7}}[1.1]\] Hence \[pH=7-0.0414=6.96\].You need to login to perform this action.
