Question

what is the difference between a simple acid, dilute acid and concentrated acid?

Answer 1

In dilute acids, the amount of solute is less while that of solvent is more. Dilute acids are those in which amount of acid is less, but water is more. The number of H⁺ ions in such solutions is low. In concentrated acids, the amount of solute is more while that of solvent is less. Concentrated acids are those in which have more amount of acid and less amount of water. The number of H⁺ ions in such solution is also high.
