Detailed explanation-1: -Ionic compounds are soluble in water but insoluble in kerosene because: Q. Why are ionic chemicals water-soluble but kerosene insoluble?
Detailed explanation-2: -Ionic compounds dissolve in polar solvents, especially water. This occurs when the positive cation from the ionic solid is attracted to the negative end of the water molecule (oxygen) and the negative anion of the ionic solid is attracted to the positive end of the water molecule (hydrogen).
Detailed explanation-3: -1. Yes, most ionic compounds are soluble in water.
Detailed explanation-4: -Which ions are soluble? Na+, K+, etc. Cl-, Br-, I-, etc. *Lead halides are soluble in hot water.
Detailed explanation-5: -Water dissolves many ionic compounds and some covalent compounds. The mechanism by which ionic compounds and covalent compounds dissolve, however, is different. Water molecules move about continuously due to their kinetic energy.
