HELP ASAP PLEASE!!!

Identify the reactants that are Arrhenius bases, Brønsted-Lowry bases, and/or Lewis bases.

State which type(s) of bases each reactant is, and be sure to explain your answers.

NaOH(s) → Na+(aq) + OH-(aq)
HF(aq ) + H2O(l) → F-(aq ) + H3O+(aq )
H+(aq ) + NH3(aq ) → NH4+(aq )

Answer 1

Answer:-

Arrhenius bases:- NaOH

Brønsted-Lowry bases:- H2O

Lewis bases:- NH3

Explanation:-

Arrhenius bases are bases that give an OH- in water.

According to NaOH(s) → Na+(aq) + OH-(aq)

NaOH gives OH-

Hence it is Arrhenius base.

Lewis Bases are bases that donate lone pairs,

NH3 donates lone pair to H+ as per H+(aq ) + NH3(aq ) → NH4+(aq )

Brønsted-Lowry bases are bases that give the negative anion of the solvent on reacting with it.

In HF(aq ) + H2O(l) → F-(aq ) + H3O+(aq )

H2O gives F- from HF.

F- is the negative anion of the solvent HF.

Hence H2O is Brønsted-Lowry bases

Answer 2

A Lewis base donates a lone pair of electrons.

Types of acids

Bases can be classified in three main ways;

• Arrhenius system
• Browstead Lowry system
• Lewis system

In reaction 1, the base, NaOH is an Arrhenius base because it produces hydroxide ion as its only negative ion in solution.

In reaction 2, H2O is a Brownstead Lowry base because it accepted a proton from the HF molecule.

In reaction 3, NH3 is a Lewis base because it donated a lone pair of electrons to the hydrogen ion.
