We’re being asked to classify sodium chloride as a strong electrolyte, weak electrolyte, or nonelectrolytes. Recall that:
• 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–
A water solution of sodium chloride is a good conductor of electricity. Due to this property, table salt is classified as a(n):
a) weak electrolyte
c) strong electrolyte
