(b) once the ionic solid has dissolved, the anion that is formed is able to react as a base, with water as the acid. write the net acid-base reaction that occurs when dissolved nac2h3o2 reacts with water. (use the lowest possible coefficients. omit states-of-matter in your answer.)
(e) write the net acid-base reaction that occurs when hc2h3o2 is added to water.

hc2h3o2 + h2o → h3o+ + c2h3o2-
correct.
(f) what is the relative ka value for this reaction?
ka < < 1
ka ≈ 1
ka > > 1correct: your answer is correct.
(g) which species are present in the greatest concentration? (select all that apply.) --i need b and g
weak acid molecules
hydronium ions
water molecules
conjugate base ions

b C₂H₃O₂⁻ + H₂O ⇄ HC₂H₃O₂ + OH⁻

e HC₂H₃O₂ + H₂O ⇄ H₃O⁺ + C₂H₃O₂⁻

f ka<<1

g. Weak acid molecules and water molecules

Explanation:

The water molecule could act as a base and as an acid, a molecule that have this property is called as amphoteric.

b The salt NaC₂H₃O₂ is dissolved in water as Na⁺ and C₂H₃O₂⁻. The reaction of the anion with water is:

C₂H₃O₂⁻ + H₂O ⇄ HC₂H₃O₂ + OH⁻

Where the C₂H₃O₂⁻ is the base and water is the acid.

e. The reaction of HC₂H₃O₂ (acid) with water (base), produce:

HC₂H₃O₂ + H₂O ⇄ H₃O⁺ + C₂H₃O₂⁻

f. As the acetic acid (HC₂H₃O₂) is a week acid, the dissociation in C₂H₃O₂⁻ is not complete, that means that ka<<1

g. The ka for this reaction is 1,8x10⁻⁵, that means that there are more weak acid molecules (HC₂H₃O₂) than conjugate base ions. Also, the water molecules will be in higher proportion than hydronium ions.

I hope it helps!
