Ionic compounds are made up of one metal and non-metal. Like NaCl. Here, Na is Sodium and it is a metal. Cl is Chlorine And it is a non-metal. Covalent compounds are made up of non-metals. Like HCl. Both H (hydrogen) and Cl (chlorine) are non-metals.

Covalent compounds have low melting points and boiling points.
Covalent compounds do not conduct electricity
Covalent compounds dissolve in organic solvents but no dissolve in water
Ionic compounds have high melting point and boiling point
Ionic compounds do not conduct electricity in the solid stare. Ionic compounds conduct electricity when molten or dissolved in water
Ionic compounds readily dissolve in water but not dissolve in organic compounds.
Test one:
dissolve in water.
if the one which dissolves water will contain ionic compound, the other is covalent compound
Test two:
electrolysis
pour water into the compounds.
place the cathode and anode into the solutions with a electricity supply. if light bulbs lights up, the solution contains ionic compound. if not, the solution contains covalent compound
Test three:
heating.
ionic compounds are very stable to heat and will need a long time to decompose when heating it. covalent compound will melt usually very easily
