Low [H3O+]

Postby alicechien_4F » Mon Jan 20, 2020 6:34 pm

Can someone clarify what Dr. Lavelle said in lecture about how a solution with [H3O+] < 10^7 M is considered neutral? Does this only apply to acid reactions or how does it work if it is a basic solution with a lot amount of H3O+? Thanks!

What this meant is that when you add a very weak acid or a small amount of acid to a neutral solution, sometimes it does not produce enough H3O to affect the pH. This is because there is already 10^7 (H3O) in a solution of neutral water at 25 degrees Celsius.
