From the graph dimensions salt is: XY2 [X] = 1 × 10-3M [Y] = 2 × 10-3M XY2(s) leftharpoons X2+(aq.) +2Y-(aq) ksp = [X2+] [Y-]2 = (10-3) (2 × 10-3)2 = 4 × 10-9 M3

Q. The stoichiometry and solubility product of a salt with the solubility curve given below is, respectively:

$X_{2} Y, 2 \times 1 0^{- 9} M^{3}$

$X Y_{2}, 1 \times 1 0^{- 9} M^{3}$

$X Y_{2}, 4 \times 1 0^{- 9} M^{3}$

$X Y, 2 \times 1 0^{- 6} M^{3}$

From the graph & dimensions salt is : $X Y_{2}$
$[X] = 1 \times 1 0^{- 3} M$
$[Y] = 2 \times 1 0^{- 3} M$
$X Y_{2} (s) ⇌ X_{(a q .)}^{2 +} + 2 Y_{(a q)}^{-}$
$k s p = [X^{2 +}] [Y^{-}]^{2}$
$= (1 0^{- 3}) (2 \times 1 0^{- 3})^{2}$
$= 4 \times 1 0^{- 9} M^{3}$

Q. The stoichiometry and solubility product of a salt with the solubility curve given below is, respectively:

X2​Y,2×10−9M3

XY2​,1×10−9M3

XY2​,4×10−9M3

XY,2×10−6M3

From the graph & dimensions salt is : XY2​ [X]=1×10−3M [Y]=2×10−3M XY2​(s)⇌X(aq.)2+​+2Y(aq)−​ ksp=[X2+][Y−]2 =(10−3)(2×10−3)2 =4×10−9M3

$X_{2} Y, 2 \times 1 0^{- 9} M^{3}$

$X Y_{2}, 1 \times 1 0^{- 9} M^{3}$

$X Y_{2}, 4 \times 1 0^{- 9} M^{3}$

$X Y, 2 \times 1 0^{- 6} M^{3}$

From the graph & dimensions salt is : $X Y_{2}$
$[X] = 1 \times 1 0^{- 3} M$
$[Y] = 2 \times 1 0^{- 3} M$
$X Y_{2} (s) ⇌ X_{(a q .)}^{2 +} + 2 Y_{(a q)}^{-}$
$k s p = [X^{2 +}] [Y^{-}]^{2}$
$= (1 0^{- 3}) (2 \times 1 0^{- 3})^{2}$
$= 4 \times 1 0^{- 9} M^{3}$
