Properties and Behavior of HCl

The video explores whether HCl is ionic or covalent, concluding it is a polar covalent compound. It explains the concept of electronegativity and how the difference between hydrogen and chlorine determines the bond type. The video also discusses the behavior of HCl in water, where it dissociates into ions, yet remains classified as polar covalent due to its nonmetal components.

What happens to HCl when it is dissolved in water?

• It splits into ions

• It forms a solid

• It remains unchanged

• It evaporates

What ions are formed when HCl is in water?

• H2 and Cl2

• H+ and Cl-
