How are acids and protons related? (1 point)

Question

• Acids are substances that contain more protons than bases.
• Acids are substances that contain fewer protons than bases.
• An acid can donate protons to a base when they react.
• An acid can accept a proton from a base when they react.

Answer 1

The correct statement is: An acid can donate protons to a base when they react.

This is based on the Brønsted-Lowry theory of acids and bases, which defines an acid as a substance that donates protons (H⁺ ions) and a base as a substance that accepts protons.
