Question

Choose the aqueous solution below with the highest freezing point. These are all solutions of nonvolatile solutes and you should assume ideal van't Hoff factors where applicable. Choose the aqueous solution below with the highest freezing point. These are all solutions of nonvolatile solutes and you should assume ideal van't Hoff factors where applicable. 1. 0.200 m HOCH2CH2OH 2. 0.200 m Na3PO3 3. 0.200 m Ba(NO3)2 4. 0.200 m Mg(ClO4)2 5. These all have the same freezing point. (please explain reasoning)

Answer 1

The freezing Point of water is lowered when m ore particles dissolvedin solution. Here, molarity of allmolecules are same.The substance which produces lessparticle in solution has highest freezing point. 1. HOCH CH OH is covalent andit doen not ionize lmol of molecules 4mol of ions 3 mol of ions 3mol of ions. HOCH,CHOH produces less particles in soluti on.
