Answer
Answer:
B. $HCO_3^-$
Explanation:
Step1: Recall Bronsted - Lowry base definition
A Bronsted - Lowry base is a substance that accepts a proton ($H^+$).
Step2: Analyze the reaction
In the reaction $HCO_3^-+H_2S\rightarrow H_2CO_3 + HS^-$, $H_2S$ donates a proton to $HCO_3^-$.
Step3: Identify the base
Since $HCO_3^-$ accepts a proton from $H_2S$ to form $H_2CO_3$, $HCO_3^-$ is the Bronsted - Lowry base.
