Predict whether the following compounds are soluble or insoluble in water.
Soluble Insoluble
PbCl2 BaSO4 eCO3 KNO3 AgNOs CuBr2
We know that like dissolves like so ionic compounds dissolves in ionic solvent such as water
So PbCl2 is soluble in water.
In Alkaline earth metal, Hydration enthalpy decreases down the group from Be2+ to Ba2+.But the Lattice energy of the Sulphates remains the same.So BaSO4 does not soluble in water.
Most ionic salts containing CO32- are insoluble in water with the exception of those involving ammonium or group one metallic.So FeCO3 is insoluble in water.
KNO3 is soluble in water .
AgNO3 is soluble in water.
CuBr2 is also soluble in water.
