The Ph OF NEUTRAL WATER AT `25^(@)C` is `7.0.` As the temperature increases, ionisation of water increases, however the concentration of `H^(+)` ions nad `OH^(-)` ions equal. What will be the ph of puire water at `60^(@)C`?

Options

A. Equal to 7.0
B. Greater than 7.0
C. Less than 7.0
D. Equal to zero

Answer

C

Explanation

Since ionisation of water increases upon increasing the temperature, `[H^(+)]` increases. The ph of the solution therefore, decreases and beocomes less than 7.
