Based on Arrhenius concept, define acid and bases and give an example for each.

Answer»

Solution :According to Arrhenius, an ACID is a substance that dissociates to give hydrogen ions in water For example, `HCI, H_2SO_4` etc. are acids. Their DISSOCIATION in aqueous solution is expressed as
`HCI_((g))overset(H_2O)(hArr) Ca_((aq))^(2+)+2OH_((aq))^(-)`
Similarity a base is a substance that dissociates to give hydroxyl ions in water. For example, substance LIKE `NAOH,Ca(OH)_2` etc. are bases.
`Ca(OH)_2 overset(H_2O)(hArr) Ca_((aq))^(2+)+2OH_((aq))^(-)`
