Chemistry

Question 1

what is a colligative property

Answer 1

a property of a solution that is dependent on the ratio between the total number of solute particles (in the solution) to the total number of solvent particles

Question 2

what is Freezing point depression

Answer 2

refers to the lowering of the freezing point of solvents upon the addition of solutes

Question 3

what is Boiling point elevation

Answer 3

refers to the increase in the boiling point of a solvent upon the addition of a solute

Question 4

what is Osmotic pressure

Answer 4

defined as the minimum pressure applied to a solution to stop the flow of solvent molecules through a semipermeable membrane

Question 5

what is vapor pressure lowering

Answer 5

After adding solute, the vapour pressure of the solution is found to be lower than that of the pure liquid at a given temperature.

Question 6

Factors Affecting Solubility

Answer 6

1. Temperature
2. Forces and Bonds
3. Pressure

Question 7

what are exothermic reactions

Answer 7

a reaction that releases energy from the system in the form of heat

Question 8

what are endothermic reactions

Answer 8

a reaction where the system absorbs energy from its surroundings in the form of heat
