We’re being asked to determine the solute particles present in aqueous solutions of each of the given compound. Recall that:
• Strong electrolytes: dissociate completely in water; include soluble ionic salts, strong acids, and bases
• Weak electrolytes: doesn’t dissociate completely in water; include weak acids and bases
• Nonelectrolytes: doesn’t dissociate at all; include molecular compounds
Ethylene glycol, C2H6O2, is a nonelectrolyte:
Ethylene glycol, C2H6O2, is a nonelectrolyte; hypochlorous acid, HClO, is a weak electrolyte; and iron(III) sulfate, Fe2(SO4)3, is a strong electrolyte. What are the solute particles present in aqueous solutions of each compound? (Select all that apply.)
OH- O2- C2H6O2 HC2H6O2+ C2H5O2- H+ OH- O2- ClO- HCl2+
HClO H+ Fe3+ Fe2(SO4)3 Fe2+ SO42- SO43- S2O42-
