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

Respuesta :

Answer: The correct answer is 'increases to 100 times the original concentration'.

Explanation:

let the initial pH be x

The original concentration of [tex][H^+][/tex] initially present be y

[tex]x=-log[y][/tex]...(1)

Final concentration of [tex][H^+][/tex] when pH reduced by 2 be z

[tex]x-2=-log[z][/tex]...(2)

Putting the value of 'x' from (1) into (2) we get :

[tex]-log[y]-2=-log[z][/tex]

[tex]z=10^2y=100y[/tex]

When pH of a solution decreases by 2.0, hydronium ion concentration of the solution increases to 100 times the original concentration



Answer:

B, is the answer
