Question

How do acids and bases affect the hydrogen ion concentration of a solution?

Answer 1

Well, acids tend to have a lot of `H^+` ions.

Explanation:

According to the Arrhenius acid-base theory, acids dissociate into `H^+` ions in aqueous solutions, while bases dissociate into `OH^-` ions in aqueous solutions. So from here, we can say that acids contain a lot of `H^+` ions, while bases contain less `H^+` ions and more `OH^-` ions.
