Answer: The correct answer is 'increases to 100 times the original concentration'.
Explanation:
let the initial pH be x
The original concentration of
initially present be y
...(1)
Final concentration of
when pH reduced by 2 be z
...(2)
Putting the value of 'x' from (1) into (2) we get :
![-log[y]-2=-log[z]](https://tex.z-dn.net/?f=-log%5By%5D-2%3D-log%5Bz%5D)
![z=10^2y=100y](https://tex.z-dn.net/?f=z%3D10%5E2y%3D100y)
When pH of a solution decreases by 2.0, hydronium ion concentration of the solution increases to 100 times the original concentration
