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. C6H12O6(l) b. C6H12O6(s) c. LiCl(aq) d. LiCl(s)
Electricity What do you need to conduct electricity? Mobile, charged particles!!!!
Electrolyte = 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 (NH3 NH4+ + OH-) - Acids (start with H except H2O H2O2 or end in COOH) Nonelectrolyte substance that dissolves in water to form solution that does not conduct electricity - basically all covalent except acids and bases
Electrolyte vs. Nonelectrolyte Which solution conducts a current?
