Answer: B. Water

Explanation:

Solar, water and wind are the renewable resources. They are abundantly available in nature and are replenishable. Due to human intervention the most affected resource is water. As water is required for various activities by human society. With the use in large scale such a resource is also contaminated by humans due to sewage discharge in water bodies, industrial discharge, disposal of wastes and even the cremation of humans a ritual practice is performed in water bodies. This will likely to deplete the available freshwater for future.

For which of the following aqueous solutions would one expect to have the largest van’t Hoff factor (i)? a. 0.050 m NaCl b. 0.50
ira [324]

Answer:

The van't hoff factor of 0.500m K₂SO₄ will be highest.

Explanation:

Van't Hoff factor was introduced for better understanding of colligative property of a solution.

By definition it is the ratio of actual number of particles or ions or associated molecules formed when a solute is dissolved to the number of particles expected from the mass dissolved.

a) For NaCl the van't Hoff factor is 2

b) For K₂SO₄ the van't Hoff factor is 3 [it will dissociate to give three ions one sulfate ion and two potassium ions]

Out of 0.500m and 0.050m K₂SO₄, the van't hoff factor of 0.500m K₂SO₄ will be more.

c) The van't Hoff factor for glucose is one as it is a non electrolyte and will not dissociate.
