**Question:**

What is the conjugate base in the following reaction: HCl (aq) + H₂O (l) ⇌ Cl⁻ (aq) + H₃O⁺ (aq)?

**Explanation:**

In this chemical equation, hydrochloric acid (HCl) acts as an acid and donates a proton (H⁺) to water (H₂O). As a result, chloride ion (Cl⁻) is formed. The conjugate base of an acid is the species that is left after the acid has donated a proton. Therefore, in this reaction, the conjugate base of HCl is Cl⁻. 

This equilibrium reaction shows the reversible process where HCl dissolves in water, producing hydronium ions (H₃O⁺) and chloride ions (Cl⁻). Here, HCl is the acid, and Cl⁻ is its conjugate base.

Expert Solution
Step 1

Given -

HCl(aq) + H2O(I) <-> Cl- (aq) + H3O+(aq)

-> Conjugate base is formed when acid can donate it's acidic proton to base .

-> Conjugate acid is formed when base can accepts acidic proton .
