A) 7.0
B) 7.13
C) 6.0
D) 6.63
Correct Answer: D
Solution :
\[[{{H}^{+}}]\,[O{{H}^{-}}]\,={{10}^{-13.26}}\] \[\therefore \] \[[{{H}^{+}}]\,=\,[O{{H}^{-}}],\] \[\therefore \] \[{{[{{H}^{+}}]}^{2}}={{10}^{-13.26}}\] \[[{{H}^{+}}]={{10}^{\frac{-13.26}{2}}}\] pH = 6.63.You need to login to perform this action.
