Meadow Freeman · Answer 1

A. Substances that release protons when they dissolve in water are termed acids and result in a pH lower than 7

Explanation:

An acid when in water releases a proton (H+) while the base in water releases an hydroxide (OH-) ion. The hydroxide ion released by the base then accepts the Proton released by the acid.

An acidic substance is known to have a pH of 0-6.9 while basic substances have a pH of 7.1-14.0.

This makes option A correct.

Rafael Simon · Answer 2

Answer: A

Explanation:

An acid is a substance that dissolves in water to produce proton (H + ), which then combines with Water molecule (H2O) to give Hydroxonium ion (H3O + ).

Acid also have a pH value below 7 on the pH scale.
