A) =7
B) < 7
C) > 7
D) None of these
Correct Answer: B
Solution :
The dissociation of water is an endothermic reaction therefore \[{{K}_{W}}\](ionization) increases with the increase in temperature. The pH of pure water at \[80{}^\circ C\] de- creases due to the rise in temperature and becomes less than 7 (due to increase in \[{{H}^{+}}\]concentration). Hence, the correct option is [b].You need to login to perform this action.
