The pH of a solution decreases by 2.0. How does the hydronium ion concentration of the solution change?
2 answers:
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 :
When pH of a solution decreases by 2.0, hydronium ion concentration of the solution increases to 100 times the original concentration
