Question

which of the following solution has maximum value of freezing point

1. H2O

2. 0.1 M NaCl

3. 0.01 NaCl

4. 10.001 M NaCl

Answer 1

Pure water has the maximum freezing point. The addition of non-volatile solute such as NaCl decreases the freezing point of water. So, NaCl solutions will have lower freezing points than pure water.
