Q. If the ionic product of water $\left( K_{w} \right)is\ 1.96 \times 10^{- 14}$ at $35℃$, what is its value at $10℃$ ?
A) $1.96 \times 10^{- 14}$
B) $3.92 \times 10^{- 14}$
C) $2.95 \times 10^{- 15}$
D) $1.96 \times 10^{- 13}$
Explanation
(c)
Ionic product $\propto$ temperature
So, if the temperature is decreased, the value of ionic product will definitely be less than before.
