Options:
  • A $1.96 \times 10^{-14}$
  • B $3.92 \times 10^{-14}$
  • C $2.95 \times 10^{-15}$
  • D $1.96 \times 10^{-13}$

The correct answer is: $2.95 \times 10^{-15}$
Ionic product $\propto$ Temperature
So, if the temperature is decreased, the value of ionic product will definitely be less than before.
