If the pH of a solution changes from 2 to 4, it means that the solution has become less acidic and more basic.
The pH scale is logarithmic, so every unit change in pH represents a tenfold change in hydronium ion concentration. In this case, as the pH increases from 2 to 4, it means that the hydronium ion concentration decreases by a factor of 10^2, which is 100.
Therefore, the hydronium ion concentration decreases by 100 times when the pH of a solution changes from 2 to 4.
If the pH of a solution changes from 2 to 4 then the hydronium ion concentration does what
