pOH=14pH

Explanation:

You can simply find the pH from the concentration of H+ which is equal to:

[H+]=[HCl]0

Then, pH=log[H+]

From the water dissociation constant kw=[H+][OH]=1.0×1014 we can take the log of both parties, we get:

logkw=log[H+]log[OH]=14

knowing that pH=log[H+] and pOH=log[OH], therefore,

pH+pOH=14pOH=14pH
