question 24
1 point

Explanation:

The pH scale ranges from 0 - 14. Acids are substances that release hydrogen ions (\(H^{+}\)) in solution. A lower pH (less than 7) indicates a higher concentration of \(H^{+}\) ions, so acids have a pH less than 7. Bases are substances that release hydroxide ions (\(OH^{-}\)) or accept \(H^{+}\) ions. A higher pH (greater than 7) indicates a lower concentration of \(H^{+}\) ions (or higher \(OH^{-}\) concentration in some cases), so bases have a pH greater than 7. Neutral solutions have an equal concentration of \(H^{+}\) and \(OH^{-}\) ions, which occurs at pH = 7.

Answer:

Acids have a pH less than 7; bases have a pH greater than 7; neutral solutions have a pH equal to 7.
