1.
The depression in freezing point caused by a 1M NaCl solution is 0.0123°C. What will be the depression in freezing point caused by 1M glucose solution?

2.
When HgI[ss]2[/ss] is mixed with aqueous solution of KI then freezing point ................. .([i]increases/decreases/remains same[/i])

3. ([i]True/False[/i])
When a liquid and its vapours are at equilibrium and the pressure is suddenly decreased cooling occurs.

[b]Justify your answers.[/b]

Ans 1..the depression in freezing point caused is half as that caused by NaCl..due to the van't Hoff factor..which is 2 for NaCl and 1 for glucose...

2)inc
becoz compelx formed
