Answer
Arrhenius Theory — Acids are substances which dissociate in aqueous solution to give H+ ions.
Strong acids dissociate almost completely, while weak acids dissociate partially.
Lowry – Bronsted's theory — Acids are proton donors and bases are proton acceptors [proton = H+].
HCl [aq.] ⟶ H+ + Cl- [acid - proton donors]
NH3 + H+ ⟶ NH4+ [bases - proton acceptors]
