Question

Sucrose, C12H22O11, is a nonelectrolyte; formic acid, HCHO2, is a weak electrolyte; and ammonium chloride, NH4Cl, is a strong electrolyte. What are the solute particles present in aqueous solutions of each compound? (Separate substances in a list with a ",".)

If 0.1 mol of each compound is dissolved in solution, which one contains 0.2 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?

Explanation / Answer

Solute particles present:

C12H22O11: C12H22O11

HCHO2: HCHO2, H+, CHO2-

NH4Cl: NH4+, Cl-


Strong electrolyte NH4Cl fully dissociates:

0.2 mol solute particles: NH4Cl


Nonelectrolyte C12H22O11 does not dissociate:

0.1 mol solute particles: C12H22O11


Weak electrolyte HCHO2 partially disssociates:

between 0.1 and 0.2 mol solute particles: HCHO2
