Assuming equal concentrations and complete dissociation, rank these aqueous solutions by their freezing points; cocl3, k2co3, nh4i

The order of increasing freezing points is  

Explanation:

The expression of depression in freezing point is given as:

where,

= Depression in freezing point

i = Van't Hoff factor

= freezing point constant

m = molality

Let the molarity of the given solutions is '1 m'

For the given options:

Value of i = 4

So, molal concentration will be =

Value of i = 3

So, molal concentration will be =

Value of i = 2

So, molal concentration will be =

As, the molal concentration of is the highest, so its freezing point will be the highest.

Hence, the order of increasing freezing points follows:
