The ph of a solution decreases by 2.0. how does the hydronium ion concentration of the solution change?

increases to 2 times the original concentration
increases to 100 times the original concentration
decreases to 1/100 of the original concentration
decreases to 1/2 of the original concentration

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

answer; i do believe the correct answer is (river); /// good luck

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.
