JEE Mains · Chemistry · STD 11 - 6.2. Equilibrium - II (icon Equilibrium)

\(\mathrm{A}_{3} \mathrm{~B}_{2}\) is a sparingly soluble salt of molar mass \(\mathrm{M}\left(\mathrm{g} \,\mathrm{mol}^{-1}\right)\) and solubility \(\mathrm{x}\, \mathrm{g}\, \mathrm{L}^{-1}\). The solubility product satisfies \(\mathrm{K}_{\mathrm{sp}}=a\left(\frac{\mathrm{x}}{\mathrm{M}}\right)^{5}\). The value of \(a\) is ...... . (Integer answer)

Answer & Solution

Correct Answer

(D) \(108\)

Step-by-step Solution

Detailed explanation

\(\mathrm{A}_{3} \mathrm{~B}_{2}(\mathrm{~s}) \rightleftharpoons 3 \mathrm{~A}_{(\mathrm{xa})}^{+2}+2 \mathrm{~B}_{(4)}^{-3}\) \(\quad\quad\quad\quad\quad\quad3 \mathrm{~s}\quad\quad \quad 2 \mathrm{~s}\) \(\mathrm{~K}_{\mathrm{sp}}=(3 \mathrm{~s})^{3}(2 \mathrm{~s})^{2}\)…
