4.3.2 - Hydrogen Chloride

Question 1

Equation for forming hydrogen chloride:

Answer 1

Hydrogen➕Chlorine➡️Hydrogen (g) (g) chloride(g) - green colourless

Question 2

What type of bonding does Hydrogen Chloride contain !?

Answer 2

. Hydrogen chloride is a covalently bonded, simple molecular substance

Question 3

Why is Hydrogen Chloride a gas !?

Answer 3

. It is a gas because it has a low boiling point due to weak intermolecular forces

Question 4

What happens when you dissolve Hydrogen chloride into water!?

Answer 4

. HCl(g) dissolves to form HCl(aq)

. HCl(aq) dissociates to form H+(aq)

. The H+(aq) is acidic

. HCl(aq) is called “hydrochloric acid”

Question 5

What happens when you dissolve Hydrogen chloride into methylbenzene!?

Answer 5

. HCl(g) dissolves to form HCl(org)

. HCl(org) cannot dissociate

. There is no H+(org)

. HCl(org) is not acidic
