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

\(25^{\circ} \mathrm{C}\) पर कैल्सियम फॉस्फेट (आण्विक द्रव्यमान, \(\mathrm{M}\) ) की जल में विलेयता \(\mathrm{W}_{\mathrm{g}}\) प्रति \(100 \mathrm{~mL}\) है। \(25^{\circ} \mathrm{C}\) पर इसका विलेयता गुणनफल लगभग होगा

  1. A \(10^7\left(\frac{\mathrm{W}}{\mathrm{M}}\right)^3\)
  2. B \(10^7\left(\frac{\mathrm{W}}{\mathrm{M}}\right)^5\)
  3. C \(10^3\left(\frac{\mathrm{W}}{\mathrm{M}}\right)^5\)
  4. D \(10^5\left(\frac{\mathrm{W}}{\mathrm{M}}\right)^5\)

Answer & Solution

Correct Answer

(B) \(10^7\left(\frac{\mathrm{W}}{\mathrm{M}}\right)^5\)

Step-by-step Solution

Detailed explanation

\(\mathrm{S}=\frac{\mathrm{W} \times 10}{\mathrm{M}}\) \(\mathrm{Ca}_3\left(\mathrm{PO}_4\right)_2(\mathrm{~s}) \underset{3 \mathrm{~s}}{\rightleftharpoons} 3 \mathrm{Ca}^{2+}(\text { aq. })+2 \mathrm{PO}_4^{3-}(\text { aq. })\)…
