Question

For c2h3o2−, write an equation that shows how the anion acts as a base.

Answer 1

Explanations:- Acetate ion is a conjugate base of a weak acid(acetic acid). From Bronsted-Lowry concept of acid and base, "Acids are proton donor where as bases are proton acceptors.

To work as a base, acetate ion would be accepting a proton. Water is an amphoteric compound means it could act as an acid as well as a base. So, let's write the reaction of acetate ion with water to show how it acts as a base.

`C_2H_3O_2^-(aq)+H_2O(l)\rightleftharpoons HC_2H_3O_2(aq)+OH^-(aq)`

In the above reaction, acetate ion has accepted a proton from water means its a base and since water has donated a proton so its an acid.

Acetic acid is the conjugate acid of acetate ion and hydroxide ion is the conjugate base of water.

Answer 2

The synthetic compound Zn(C2H3O2)2 is zinc acetic acid derivation. The molecular composition demonstrates that the mixes incorporate zinc, spoke to by Zn; carbon, spoke to by C; hydrogen, spoke to by H; and oxygen, spoke to by O. Below is the an equation that shows how the anion acts as a base:

C2H3O2−(aq)+H2O(l)⇌HC2H3O2(aq)+OH−(aq)
