Melting Point

 

Number 2 and number 4 melted. Just the covalent were the ones that melted first, and the ionic took longer time. This means that ionic have higher melting points.

 

Conductivity

 

The light turned only with salt, not on water nor sugar.

 

Salt is an ionic compound, sugar was a covalent compound, and water is a covalent compound. With this, we can say that ionic compounds do conduct electricity, while covalents don't.
