Question

You are given two solutions A and B. Solution A has a pH of 5.0 whereas Solution B has a pH of 9.0. Which solution is an acid and which one is a base?

Please help me

Answer 1

Solution A is an acid and solution B is a base.

I know that a pH greater than 7 is considered a base and everything under is an acid. I don't remember a whole lot from my biology class but I did happen to remember pH levels
