Which of the following solutions have lowest freezing point?
a) 0.1NaCL
b) 0.01 M NaCL
c) 1M NaCL
d) 0.001M NaCL
Depression in freezing point directly proportional to molarity of solution.So, more conc. of solute more depression in freezing point. So, as we decrese the temp. 0.001M NaCl freezes first & 1M NaCl freezes in last.
