A) 6.0
B) 7.0
C) 8
D) 13
Correct Answer: B
Solution :
Total concentration of \[{{\text{H}}^{\text{+}}}\]ions \[={{10}^{-10}}+H{{O}^{-7}}\] \[(HCl)\,\,\,({{H}_{2}}O)\] \[={{10}^{-10}}(1+{{10}^{3}})=1001\times {{10}^{-10}}.\] So, \[pH=-\log (1001\times {{10}^{-10}})\] \[=10-3\] \[=7\] Hence, the correct option is (b).You need to login to perform this action.
