Question

A student stirs 2 tablespoons of honey into a glass of water. How will the addition of honey affect the water’s colligative properties?

A. The water’s osmotic pressure and vapor pressure will both increase.
B. The water’s osmotic pressure and vapor pressure will both decrease.
C. The water’s osmotic pressure will increase, and its vapor pressure will decrease. D. The water’s osmotic pressure will decrease, and its vapor pressure will increase.

Answer 1

C.The water’s osmotic pressure will increase, and its vapor pressure will decrease.

Answer 2

The answer is : C. The water’s osmotic pressure will increase, and its vapor pressure will decrease. The addition of honey will affect the water’s colligative properties, the water’s osmotic pressure will increase. Since honey and water solution will easily pass through the semi-permeable solution, it follows that the vapour pressure will decrease.
