Question

What effect does temperature has on ionization and pH of water?
  1. Ionization increases but pH decreases with increase in temperature
  2. Ionization and pH deccreases with increase in temperature
  3. Ionization and pH increases with increase in temperature
  4. Ionization decreases but pH increases with increase in temperature

A
Ionization and pH increases with increase in temperature
B
Ionization decreases but pH increases with increase in temperature
C
Ionization increases but pH decreases with increase in temperature
D
Ionization and pH deccreases with increase in temperature
Solution
Verified by Toppr

The extent of ionization varies with temperature, it increases with an increase in temperature. Thus the concentration of H3O+ ions increases with increase in temperature. Hence, its pH decreases with increase in temperature.
