pH plus pOH equals 14.
pH+pOH=14 -> pH+5.010=14 -> pH= 8.99
By definition pH = -log[H+], so pH = -log(4.9*10-4) = 3.31Only at 25oC: pOH = 14.00 - pH, so 14.00 - 3.31 = 10.69 = pOH
Yes, if both solutions are at 25oC then in both solutions this is valid: pH + pOH = 14.0
3.2
1.79x10^-14 M
The pOH of that is 4
pH + pOH = 14 If the pH is 3.4, the pOH is 10.6
