Answer

Answer:

B. $Ba(OH)_2$

Explanation:

Step1: Recall base - definition

A base is a substance that can accept a proton ($H^+$) or donates hydroxide ions ($OH^-$) in a reaction.

Step2: Analyze reactants

In the reaction $H_2S + Ba(OH)_2\rightarrow2H_2O+BaS$, $Ba(OH)_2$ dissociates to give $Ba^{2 +}$ and $2OH^-$. The $OH^-$ ions can react with $H^+$ from $H_2S$. So $Ba(OH)_2$ acts as a base.

Step3: Analyze other compounds

$H_2S$ is an acid as it can donate $H^+$; $H_2O$ is a product of the acid - base reaction; $BaS$ is a salt formed from the reaction of the acid and base.
