• Strong electrolytes: dissociate completely in water; include soluble ionic salts, strong acids, and bases
• Weak electrolytes: doesn’t dissociate completely in water; include weak acids and bases
• Nonelectrolytes: doesn’t dissociate at all; include molecular compounds
Ethanol, CH3CH2OH, is a nonelectrolyte; ammonia, NH3, is a weak electrolyte; and scandium(III) sulfate, Sc2(SO4)3, is a strong electrolyte.
If 0.1 mol of each compound is dissolved in solution, which one contains about 0.5 mol of solute particles, which contains 0.1 mol of solute particles, and which contains somewhere between 0.1 and 0.2 mol of solute particles?
0.5 mol solute particles ____________________
0.1 mol solute particles _____________________
Between 0.1 and 0.2 mol solute particles _________________
