Question
Mg is not precipitated in V group because :
Options
A.MgCO3 is soluble in water.
B.Ksp of MgCO3 is high.
C.MgCO3 is soluble in NH4OH.
D.None.
Solution
As the concentration of CO32- ions provided by (NH4)2CO3 in presence of NH4Cl and ammonia is not just sufficient to precipitate the Mg as MgCO3 because of its high KSP value.
