A) =7
B) <7
C) > 7
D) none of these
Correct Answer: B
Solution :
The dissociation of water is an endothermic reaction therefore \[{{K}_{W}}\] (ionisation) increase with increase in temperature. The pH of pure water at \[80{{\,}^{o}}C\]decrease due to rise in temperature and become less than 7 (< 7) (due to increase in \[{{\text{H}}^{\text{+}}}\] concentration)You need to login to perform this action.
