Homework Help: Chem

Posted by Kim on Monday, April 30, 2007 at 8:03pm.

a chemist is asked to identify 2 solutions whose labels have peeled off. One is known to contain 1.0 mol of NaCl, the other is 1 mol of Na2CO3. Both solutes are dissolved in 1 kg of water. If the chemist measures the freezing point of each solution, can it identify which is which??

The freezing point depression is .52C *times a constant, and the constant is dependent on the ions per moleule. NaCl breaks into two ions, and sodium carbonate breaks into three. So the freezing point will be different by .52C.
