Quiz on Hydrogen Chloride

Hydrogen chloride is a:

• Covalent compound

• Ionic compound

• Metallic compound

• Complex compound

In HCl gas, the type of bond present is:

• Ionic

• Covalent polar

• Metallic

• Hydrogen bond

Hydrogen chloride is soluble in water because:

• It reacts with water

• It is ionic

• It forms hydrogen bonds

• It is a strong oxidizing agent

Aqueous solution of HCl is known as:

• Hydrochloric acid

• Sulphuric acid

• Nitric acid

• Acetic acid
