6-2.Equilibrium-II (Ionic Equilibrium)
medium

$Mg{(OH)_2}$ ની જલીય દ્રાવણમાં દ્રાવ્યતા $x$ હોય, તો તેનો  $K_{sp}$ ......... થશે.

A

$4{x^3}$

B

$108{x^5}$

C

$27{x^4}$

D

$9x$

(AIEEE-2002)

Solution

(a) $Mg{(OH)_2}⇌\mathop {M{g^{ + 2 }}}\limits_{(X)\,\,\,} + \mathop {2O{H^ – }}\limits_{{{(2X)}^2}} $

${K_{sp}} = 4{X^3}$
