Question

HF + H_2O H_3O^+ + F^- H_2O is a base, and HF is its conjugate acid. H_2O is an acid, and HF is the conjugate base. HF is an acid and F^- is its conjugate base. HF is a base, and H_3O^+ is its conjugate acid. HF is a base, and F^- is its conjugate acid. Based on the reactions we have studied, ammonia can be considered as_. an Arrhenius base(only) a Lewis base(only) a Bronsted-Lowry base(only) both an Arrhenius base and a Lewis base both a Bronsted-Lowry base and a Lewis base What is the basis for referring to "H^+" as a proton? The Arrhenius definition of an acid The Bronsted-Lowry definition of an acid The Lewis definition of an acid H^+ exists as a bare proton None of the above

Explanation / Answer

Question - 5

Answer - HF is acid and F- is its conjugate base

because acid is proton donor and after donation of proton form conjugate base

Question - 6

Answer - both bronsted - lowery base and lewis base

because ammonia give lone pair of electron therefore lewis base as well as accept proton therefore  bronsted - lowery base.

Question- 7

Ans- H+ exists as a bare proton

because in H+ ion there is no electron and neutron therefore exists as a bare proton.
