Question

The concentration of hydronium ions $\left(H_3{O}^{+}\right)$ decreases when a solution of an acid is diluted.

• A. True
• B. False

Answer 1

The correct option is A True

The concentration of hydronium ions decreases when an acid is diluted because on adding water the H+ ions of the acid and hydroxyl ions of water react to form water molecules and the concentration of hydronium ions decreases.

$H^{+}+O{H}^{-}\to H_{2}O$
