The pH of neutral water at 25 ^0 C is 7.0. As the temperature increases, ionization of water increases, however the concentration of H + ions and OH − ions are equal. What will be the pH of pure water at 60^0 C?

Options

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

Answer

C

Explanation

With increase in temperature the ionisation of water increases. Therefore the concentration of `H^(+)` ions increases and pH will be less than 7.0.
