Question

Define acid and base? what happens to the concentration of H3O+ when Solution of acid is diluted?​

Answer 1

Answer:

When the solution of an acid is diluted then its strength decreases as there is decrease in the concentration of hydronium (H

3

O

+

)ions. Diluting with water of an acid causes lowering of concentration of hydronium ion because of adding H

2

O but there are no excess H

+

to make it (H

3

O

). It means number of (H

O

+

) remains same but the total volume of the solution has increased thus causing the fall in concentration of hydronium ions as concentration is quantity/volume.
