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

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
