Q46 / 200 · Manipal (MET) 2010 · Chemistry

The pH of a neutral water sample is 6.5 . Then the temperature of water

  • A
    is $25^{\circ} \mathrm{C}$
  • Correct answer
    B
    is more than $25^{\circ} \mathrm{C}$
  • C
    is less than $25^{\circ} \mathrm{C}$
  • D
    can be more or less than $25^{\circ} \mathrm{C}$

Solution

pH varies inversely with temperature. Thus, if the pH of neutral water is 6.5 , the temperature of water is more than $25^{\circ} \mathrm{C}$.

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