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:

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

they are all solids.
