The [OH-] concentration of a LiOH solution is 0.58 M. Calculate the pH of this solution.

Answer 1

We are given the concentration of hydroxide ions, [OH^-], so we can first calculate the pOH of the solution by using the relationship pOH = -log[OH^-]. We can then calculate the pH from there by using the relationship pH + pOH = 14.00.

pOH = -log[OH^-]

pOH = -log(0.58)

pOH = 0.24...

pH + pOH = 14.00

pH = 14.00 - pOH

pH = 14.00 - 0.24...

pH = 13.76

The pH of the solution is 13.76
