We’re being asked to classify each given compound as a strong electrolyte, weak electrolyte, or nonelectrolytes.
• Strong electrolytes: dissociate completely in water; include soluble ionic salts, strong acids, and bases
a. Ionic salts: those that follow the rules of being soluble in solubility rules
b. Strong acids: HCl, HBr, HI, HNO3, H2SO4, HClO4, HClO3
c. Strong bases: Group 1A and 2A (Ca and lower) metals paired with OH–, H–, O2–, or NH2–
• Weak electrolytes: doesn’t dissociate completely in water; include weak acids and bases
a. Weak acids: include HF, HC2H3O2, HNO2, H2CO3, H3PO4
b. Weak bases: Be(OH)2, Mg(OH)2, NH3, NH4OH
• Nonelectrolytes: doesn’t dissociate at all; include molecular compounds
a. Alcohols: composed of carbon and hydrogen with a –OH group
b. Sugars: for example C6H12O6 (glucose) and C12H22O11 (sucrose)
c. Water (H2O)
Aqueous solutions of three different substances, AX, AY, and AZ, are represented by the three diagrams below.
Identify each substance as a strong electrolyte, weak electrolyte, or nonelectrolyte.
