Q15 / 160 · AP EAMCET 2003 · Chemistry
If the ionic product of water $\left(K_w\right)$ is $1.96 \times 10^{-14}$ at $35^{\circ} \mathrm{C}$, what is its value at $10^{\circ} \mathrm{C}$ ?
- A$1.96 \times 10^{-14}$
- B$3.92 \times 10^{-14}$
- Correct answerC$2.95 \times 10^{-15}$
- D$1.96 \times 10^{-13}$
Solution
Ionic product $\propto$ Temperature
So, if the temperature is decreased, the value of ionic product will definitely be less than before.
Hence, the correct answer is option: 'C'.
