Acid and Bases Help

Post by skycracker00 »

Can anyone tell me what I'm doing wrong here? For the [H3O+] and [OH-], I'm calculating their pH by simply inserting the given numbers into the -log equation but I feel like that's wrong. How can I find the pH values for those ones? Thanks.

You forgot the equilibrium for water, if you have concentration around 10^-7
