Answer :
The compound that has been soluble in water will be LiCl. Thus option E is correct.
The compounds that form stable bonds in water and are easy to dissociate are soluble in water. Generally, ionic compounds are easily soluble in water.
- AgCl:
It has been an ionic compound, but the dissociation of AgCl will simultaneously form AgCl again making the compound insoluble in water.
- [tex]\rm \bold{PbCO_3}[/tex]:
It has been a covalent compound, thus it has been insoluble in water.
- [tex]\rm \bold{CaSO_4}[/tex]:
The compound is covalent in nature, thus it has been hard to dissociate in water.
- [tex]\rm \bold{Cu(OH)_2}[/tex]:
The copper in the compound has been hard to dissolve and precipitate in the solution.
- LiCl:
It has been an ionic compound and can be easily dissociated in the water.
Thus the compound that has been soluble in water will be LiCl. Thus option E is correct.
