Question

20. If the ionic product of water is 1.96 x 10-14 at
35°C, What is its value at 10°C
1. 1.96 x 10-14 2. 3.92 x 10-14
3. 2.95 x 10-15
4. 1.96 x 10-13​

Answer 1

Answer:

option (3) is correct

=$2.95*10^{-15}$

Answer 2

Explanation:

Initial ionic product is given at 30°C they are asking about 10°C it means temperature decreased to solve this problem we use

IONIC PRODUCT OF WATER DECREASES WITH DECREASE IN TEMPERATURE AND INCREASES WITH INCREASE IN TEMPERATURE

so our answer should be less than the value at 35°C

so option 3 satisfies our condition

THEREFORE YOUR ANSWER IS 2.95×10^-15

I hope you are satisfied by my answer
