Predict whether the following compounds are soluble or insoluble in water.
Soluble Insoluble
NH4Br AgNO3 BaSO4 CoBr2 AgBr CuCO3
NH4Br is soluble in water because it is ionic in nature and is highly sublimable to form ammonia and ammonia is highly soluble in water
AgNO3 is also highly soluble in water as it forms Ag+1 and NO3- in water being ionic in nature
BaSO4 is insoluble in water as it forms a white precipitate , sulphates of heavy metal salts are insoluble except Be and Mg
CoBr2 is soluble in water (and is also readily soluble in organic solvent , it has ionic character and covalent character too so it is soluble in both)
AgBr is pale yellow precipitate and is insoluble in water
CuCO3 is insoluble in water , it can be soluble in Dil.HCl
As CuCO3 is basic in nature and it can react with acids to form salts.
