Respuesta :
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.
Answer:
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.
