Q59 / 180 · AIIMS 2001 · Chemistry

When the temperature of reactions will increase then the effect on $\mathrm{pH}$ value will

  • A
    increase
  • Correct answer
    B
    decrease
  • C
    first increases then decreases
  • D
    remains same.

Solution

As the temperature increases, the dissociation of water in solution increases. Hence the $\mathrm{H}^{+}$ion conc. increases and $\mathrm{pH}$ of the solution decreases with increase in temperature.

Hence, the correct answer is option: 'B'.
