By what factor does [h+ ] change for each ph change? (a) 3.20 units

The [H+] change for pH change of 3.20 = 1584.89.

What is pH?

pH is potential hydrogen. pH is a scale for measurement of acid and base.

The pH equation is

Now, assume the initial pHo is x

The pH after change would be  x + 3.20

Calculating the pH after change

Thus, the pH change is 1584.89.

When a change in PH = 10^-ΔPH
so the change = 10^-3.2
change depends on two factor 0.00063 (10^-3.2)and factor 1585 (10^3.2)depending on the way which the change goes.if PH change from PH=0 to PH= 3.2 so the change is decreasing from concentration from 1 mol to 0.00063 and if PH change from PH = 3.2 to PH=0 so the change is increasing by a factor of 1585.

the answer is true.

this statement is true.
