Solution

The correct option is A
True

$B a S O_{4} (s) ⇌ B a^{2 +} (a q) + S O_{4}^{2 -} (a q)$

$K_{s p} (B a S O_{4})$ = $1 \times 10^{- 10}$

Ionic product of $B a S O_{4}$ = $[B a^{2 +}] [S O_{4}^{2 -}]$ = $2 \times 10^{- 7}$ $>$ $K_{s p}$ ( $B a S O_{4}$ )

Hence, the reaction dynamics favour precipitation.

For the given data, the reaction dynamics favour precipitation - True or False? The solution concentration of Ba2+ ions is 1 × 10−3 M and that of SO2−4 ions is 2 × 10−4 M; Ksp (BaSO4­) 1 × 10−10.

The correct option is A True BaSO4 (s)⇌Ba2+ (aq) + SO2−4 (aq) Ksp (BaSO4) = 1 × 10−10 Ionic product of BaSO4 = [Ba2+][SO2−4] = 2 × 10−7 > Ksp (BaSO4) Hence, the reaction dynamics favour precipitation.
