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

\(298\,K\) પર \(BaSO _4\) નો દ્વાવ્યતા ગુણાકાર \(1 \times 10^{-10}\) છે. \(0 .1\, M\, K _2 SO _4( aq )\) દ્વાવણ માં \(BaSO _4\) ની દ્રાવ્યતા \(.......\times 10^{-9}\, g\, L ^{-1}\) છે. (નજીકનો પૂર્ણાક) આપેલ : \(BaSO _4\) નું મોલર દળ \(233\, g\, mol\, m ^{-1}\) છે.

  1. A \(233\)
  2. B \(232\)
  3. C \(231\)
  4. D \(234\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(233\)

Step-by-step Solution

Detailed explanation

\(K _2 SO _4 \longrightarrow 2 K ^{+}+ SO _4{ }^{2-}\) \(0.1 M \quad\quad 0.2 M \quad0.1 M\) \(BaSO _4 \rightleftharpoons Ba ^{+2}+ SO _4{ }^{2-}\) \(a - S \quad S \quad S +0.1 \approx 0.1\) \(K _{ SP }= S \times 10^{-1}\) \(\Rightarrow 1 \times 10^{-10}= S \times 10^{-1}\)…
