If the ionic product of water (K(w) ) is...

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`?

A

`1. 96 xx 10^(-14)`

B

` 3.92 xx 10^(-14)`

C

` 2.95 xx 10^(-15)`

D

` 1.96 xx 10^(-13)`

Text Solution

Verified by Experts

The correct Answer is:
D
` KW downarrow " with " T downarrow `
` therefore K w lt 10 ^(-14) rArr 2. 95 xx 10 ^(-15) `
