Unformatted text preview: u-Weak Electrolyte: Aqueous solution that is partly ionized and conducts electricity to a small extent. Few ions present->e.g. Acetic Acid (HC2H302(aq))-Non Electrolyte: Aqueous solution or any substance that is not ionized and does not conduct electricity. No ions present.->e.g. Sucrose solution Strong Acid: e.g. HCl(aq) Strong Base: e.g. NaOH (Aq) Sodium Hydroxide...
