Calculate the pH of a solution with OH- concentration equal to 4.3x10-9 M. Is this solution acidic, basic, or neutral?
Ans :
[OH-] = 4.3 x 10-9 M
[H+] = (1.0 x 10-14) / (4.3 x 10-9)
= 2.3 x 10-6 M
pH = -log [H+]
= -log (2.3 x 10-6)
= 5.6
The pH below 7 are acidic and above 7 are basic , and the pH 7 is neutral.
So here the solution is acidic.
