Question

How is the concentration of hydronium ions $\sf{(H_{3}O^{+})}$ affected when a solution of an acid is diluted ?

Answer 1

Answer:

The concentration will go down proportionally on increase in volume. ... So, now we can say that the concentration of hydronium ions decreases when an acid is diluted because on adding water, the hydronium ion of acid and hydroxyl ions of water react to form water molecules and the concentration of hydronium ion decreases.

Answer 2

Answer:

The concentration of hydronium ions decreases when acid is diluted. Upon 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.
