Question

How is the concentration of hydronium ions h3o+ affected when a solution of an acid is diluted​

Answer 1

Answer:

There will be decrease in their concentration

Explanation:

When any acid is diluted it results in the decrease in the concentration of ions ( H3O+ / OH- ) .

Answer 2

Explanation:

When the solution of an acid is diluted then its strength decreases as there is decrease in the concentration of hydronium (H3O+)ions. Diluting with water of an acid causes lowering of concentration of hydronium ion because of adding H2O but there are no excess H+ to make it (H3O+).

It can be explained in 2 ways

1)First way:

H3O+ +H2O gives H3O+(aq)

Hydronium aqueous means more number of H2O (solvent) is surrounded by the Hydronium . If you add more water (i.e dilution) then more number of H2O is surrounded,as a consequence Hydronium ion concentration decreases very much in the solution pH =_log (H+) pH value increases gradually to neutral from acidic.

2)Another way

[Solute]+[solvent]=[solution]

If you add the solvent excess, concentration of solute decreases gradually (i.e hydronium ion concentration decreases)
