is neutralized by . The value of is: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
$0.1 \text{ mol } H_3PO_x$ is neutralized by $0.2 \text{ mol } NaOH$. The value of $x$ is:
Answer: B
💡 Solution & Explanation
$\text{Basicity} = \text{moles NaOH} / \text{moles acid} = 0.2 / 0.1 = 2$. <br>The dibasic acid of Phosphorus is $H_3PO_3$. Thus $x=3$.
