Question

What does the type of bond tell you about the compound's solubility and conductivity? Melting and boiling points?

Answer 1

Solubility in water, Conductivity in molten and pure state, conductivity in water and high or low melting point.

Explanation:

From properties that compounds have, you can tell what type of primary bonding they have. Here is a list of the types of properties that are present for each bond:

Covalent Bonding

• No Conductivity in its pure state
• Low mpt and bpt
• No conductivity in its molten state
• Not soluble in water
• No conductivity in water when it has been dissolved

Metallic Bonding

• Conductive in its pure state
• Good conductors of heat and electricity
• Conductive in its molten state
• High mpt and bpt
• Not soluble in water
• Conductive in water

Ionic Bonding

• Not conductivity in its pure state
• Conductive in its molten state
• High mpt and Bpt
• Soluble in water
• Can conduct electricity when dissolved in water

By testing these properties, you can come to a conclusion to what compound has what primary bond. Obviously, there are exceptions to some of these properties.
For example, Sand (Silicon dioxide, covalent bond) has a high melting point, not a low melting point.

But generally, you can tell that...

• If a compound is conductive when dissolved in water, it is ionic.
• If a compound is not conductive when dissolved in water, it is covalent.
• If a compound is conductive in its pure state, it is metallic.
