Question

The pH of a solution changes from 3.00 to 6.00. By what factor does the [H3O+] change?

Answer 1

: E) 1000 = 10^3
6-3 = 3 ==> change is 10^3
HOPE I COULD HELP

Answer 2

Answer:
`10^3`

Explanation:-

pH is the measure of acidity or alkalinity. It is also defined as negative logarithm of hydrogen ion concentration.

`pH=-log[H_3O^+]`

Given:
`pH` = 3

Thus
`3=-log[H_3O^+]`

`[H_1^+]=10^(-3)`

`6=-log[H_3O^+]`

`[H_3O^+]=10^(-6)`

`(10^(-3))/(10^(-6))=10^3`

Thus
`H_3O^+` changes by
`10^3` units.
