Solution: Classify these compounds as strong electrolytes, weak electrolytes, or nonelectrolytes.HBr, FeCl2, H2CO3

Problem

Classify these compounds as strong electrolytes, weak electrolytes, or nonelectrolytes.

HBr, FeCl2, H2CO3

Solution

We’re being asked to classify each given compound 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: include HCl, HBr, HI, HNO3, H2SO4, HClO4, HClO3

c. Strong bases: are 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: include 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)
