What is the chemical formula of sodium chloride?

NaCl

Na2Cl

NaCl2

NaCl3

Answer explanation

Since the ratio of Na+ ion: Cl- ion is 1: 1, the chemical formula is Na1Cl1. However, you do not need to show "1", hence answer is NaCl.

Select the physical properties of ionic compound.

Clue: classic example of ionic compounds is sodium chloride.

They are usually soluble (can dissolve) in water.

They are usually insoluble (cannot dissolve) in water.

They can conduct electricity in any states.

They can conduct electricity in molten (liquid) and aqueous (when dissolved in water) states.

They have low melting and boiling points.

Answer explanation

Apart from the two correct properties above, ionic compounds should have high melting and boiling points and they are usually insoluble in organic solvents (such as oil).
