Determine the hydroxide ion concentration in a solution that is 0.0004 M HCl.
Answer in units of M.
I have no idea how to start, I just need to know what I need to solve for and hoe to set it up, I know the formula pOH^-=-log[OH^-] I just don't know where to plug things in and solve

HCl is a strong acid so, determine the pH:

pH=-log[HCl]

pH+pOH=14

14-pH=pOH

Since pOH=-log[OH^-]

10^-(pOH)=[OH]
