Solution

Question 1

Solution

Answer 1

Homogenous mixture of solute and solvent

Question 2

Solubility

Answer 2

Max amount of solute that can dissolve in certain amt of solvent in givenn temp and pressure

Question 3

Types of solution based on solubility

Answer 3

1)Unsaturated solution
2)Saturated solution
3)Supersaturated solution

Question 4

Unsaturated solution

Answer 4

Contain less than max amount of solute (More solute can dissolve)

Question 5

Saturated solution

Answer 5

Contains max amount of solute (no more solute dissolve)

Question 6

Supersaturated solution

Answer 6

Contain more solute than max amount (From precipitate)

Question 7

Factors affecting the solubility

Answer 7

1)Nature of solute and solvent
2)Temperature
3)Pressure (only gases)

Question 8

Solubility of solid _____ with increase temperature

Answer 8

increases

Question 9

Solubility of gases _____ with increase temperature

Answer 9

decreases

Question 10

Why gases solubility decrease when temprature is increase?

Answer 10

Bcus at high temperature , the kinetic energy of gases is increase and gases particles are escape from solution unstead of dissolving

Question 11

When pressure is increase, the solubility of solid is increase.True or False?

Answer 11

False
There is no effect on solubility of solid when pressure is increase.

Question 12

When pressure is increase, the solubility of gases is increase.True or False?

Answer 12

True
Solubility(gases) will increase with increased pressure

Question 13

Concentration of solution

Answer 13

Measure of amount of solute that dissolved in given amount of solvent

Question 14

Molality (m)

Answer 14

m=mole of solute / kg of solvent

Question 15

Unit of molality

Answer 15

mol kg-1

Question 16

Molarity (M)

Answer 16

M= mole of solute /liter of solution

Question 17

Unit of molarity

Answer 17

mol L-1

Question 18

Normality (N)

Answer 18

N=Number of equivalent of solute / 1 liter of solution

Question 19

Normality is used to determine the concentration of ______.

Answer 19

Acids and bases

Question 20

How to find normality from molarity?

Answer 20

N=M x n (n=number of equivalent)

Question 21

What is number of equivalent of solute?

Answer 21

Amount of H+ & OH- when solute is dissociate in solution

Question 22

Percentage by mass (m/m%)

Answer 22

% by mass = gram of solute / gram of solution x 100

Question 23

How to get the mass of solution?

Answer 23

Mass of solution=mass of solute + mass of solvent

Question 24

Mass/volume percent (m/v%)

Answer 24

m/v% = gram of solute/ml of solution x 100

Question 25

Volume/volume percent (v/v%)

Answer 25

v/v%= ml of solute/ml of solution x 100

Question 26

Mole fraction (X)

Answer 26

X= Mole of solute/mole of solution

Question 27

Answer 27

1)Freezing Point depression 2)Boiling Point elevation 3)Osmotic pressure 4)Vapour pressure lowering

Question 28

Colligative property is depend only on______.

Answer 28

Number of solute particles

Question 29

Is colligative property depend on the character of solute particle?

Answer 29

No It depend only on the number of solute particles

Question 30

What is the effect of colligative property if solute with more particles is added into solution?

Answer 30

Bigger colligative effect

Question 31
