How is the concentration of hydronium ions (H3O+) affected when a solution of an acid is diluted?

Dear Student
When an acid is diluted, then the concentration of hydronium ions decreases.
This is because on dilution the overall volume of solution increases and so the number of hydronium ions per unit volume decreases.

Dear Student,

When the solution of an acid is diluted, the concentration of hydronium ions decreases because the total volume of the solution increases on addition of water.

Concentration of hydronium ions = (Volume of solute (acid) )  /  ( Volume of solution )

Hope it helps :)
