what is the conjugate base in the following reaction? hco₃⁻ + hcl → h₂co₃ + cl⁻

what is the conjugate base in the following reaction? hco₃⁻ + hcl → h₂co₃ + cl⁻
Answer
Explanation:
Step1: Recall conjugate - base definition
A conjugate base is formed when an acid donates a proton ($H^+$).
Step2: Analyze the reaction
In the reaction $HCO_3^-+HCl\rightarrow H_2CO_3 + Cl^-$, $HCl$ is an acid that donates a proton. After $HCl$ donates a proton, it forms $Cl^-$.
Answer:
A. $Cl^-$
