Question

Complete the three definitions of acids and bases.

* The Arrhenius definition of acids and bases states that in an aqueous solution, an acid [ Select ] ["proton acceptor", "an electron pair acceptor", "produces hydroxide ions", "an electron pair donor", "produces hydrogen ions"] and a base [ Select ] ["an electron pair donor", "an electron pair acceptor", "is a proton donor", "produces hydrogen ions", "produces hydroxide ions"] .

* According to the Bronsted-Lowry definition, an acid is [ Select ] ["a proton acceptor", "an electron pair donor", "a proton donor", "an electron pair acceptor", "produces hydroxide ions"] and a base is [ Select ] ["produces hydrogen ions", "a proton donor", "an electron pair acceptor", "a proton acceptor", "an electron pair donor"] .

* The Lewis model defines an acid as [ Select ] ["a proton donor", "produces hydroxide ions", "a proton acceptor", "an electron pair acceptor", "an electron pair donor"] and a base as [ Select ] ["a proton donor", "an electron pair donor", "produces hydrogen ions", "an electron pair acceptor", "a proton acceptor"] .

Answer 1

Arrhenius theory =>Acid - when a substance dissolves in H2O it releases the H+ ions i.e hydrogens (Ex- H2SO4 , HCl ... etc)

Base - when a substance dissolves in H2O it releases the OH- ions i.e hydroxide ions (Ex- NaOH , LiOH ... etc)

Bronsted-Lowry theory => Acid - these are the species which donates H+ ions => H+ ion donars ( Ex- H2SO4 , HCl ... etc)

Base - these are the species which accepts H ions => H+ ion acceptors ( Ex - NaOH , LiOH ... etc)

Lewis theory => Acid - these are the species which accepts the electron pair => electron pair acceptors ( Ex - BF3 , AlCl3 and cations ...etc)

Base - these are the species which donates the electron pair => electron pair donars (Ex- NH3 , H2O and anoins...etc )
