If the ionic product of water `(K_(w) ) is 1.96 xx 10^(-14) at 35^(circ)C` what is its value at `10^(circ)C`?

Options

A. `1.96 xx 10^(-14)`
B. `3.92 xx 10^(-14)`
C. `2.95 xx 10^(-15)`
D. `1.96 xx 10^(-13)`

Answer

C

Explanation

Ionic product of water `alpha` Temperature i.e., if temperature decrease, ionic product of water also decreases. Ionic product of water at `35^(circ)C` is `2.95 xx 10^(-15)`
