of an acid requires of for complete neutralization. What is the value of ? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Basicity} = \frac{\text{moles of NaOH}}{\text{moles of acid}} = \frac{0.2}{0.1} = 2$. <br>Among oxyacids of phosphorus with formula $H_3PO_x$, $H_3PO_3$ (phosphorous acid) is dibasic. Thus, $x = 3$.
