Question

Some molecular compounds, such as HCl, ionize completely in solution. Some molecular compounds such as HC2H3O2 do not ionize completely when they dissolve in water. Which explains their solution properties?

Answer 1

Answer and explanation;

• HCl is an example of strong acid as it ionizes completely in solution form to form hydrogen ions
• HCl ionizes in solution form into Hydrogen ions (H+) and Chloride ions (Cl-).
• HC2H3O2 , is an example of weak acids as it does not ionize completely in solution form hydrogen ions. Acetic acid is represented with opposing half arrows between the reactants and products (H+ and C2H3O2).
• Any acid that ionizes 100 percent into ions is called a strong acid while the one that does not undergo a complete dissociation is a weak acid.

Answer 2

There are two types of electrolytes: the strong and the weak electrolytes. Strong electrolytes are those which dissociates completely in solutions while weak electrolytes are those that do not. HCl is a strong electrolyte since it is a strong acid while HC2H3O2 is a weak one as it is a weak acid as well.
