Topic: Electrolytes Do Now: 1.Two grams of potassium chloride are completely dissolved in a smaple fo water in a beaker. This solutions is classified as a. an element b. a compound c. A homogeneous mixture d. a heterogeneous mixture 2. Which formula represents a mixture? a. C 6 H 12 O 6 (l)b. C 6 H 12 O 6 (s)c. LiCl(aq)d. LiCl(s) Slide 2 Electricity What do you need to conduct electricity? What do you need to conduct electricity? Mobile, charged particles!!!! Slide 3 ElectrolyteElectrolyte = ions in solution substance that dissolves in water to form solution that conducts electricity - Soluble salts (ionic compounds from table F) -Bases (metal ion + OH - ) and (NH 3 NH 4 + + OH - ) - Acids (start with H except H 2 O H 2 O 2 or end in COOH) NonelectrolyteNonelectrolyte substance that dissolves in water to form solution that does not conduct electricity - basically all covalent except acids and bases Slide 4 Electrolyte vs. Nonelectrolyte Which solution conducts a current?
