chapter 4

Question 1

solution

Answer 1

homogeneous mixture of substances consisting of solvent and solute or more.the largest material quantity is the solvent and leat amount is the solute

Question 2

the solubility process takes place easier

Answer 2

if solubility process accompanies by increase in temprature

if diffusion of componenets in solvent widely and completely

Question 3

concentration

Answer 3

the amount of solute in amount of solvent

Question 4

mass percentage of solute

Answer 4

number of grams of solute in 100g solution

Question 5

molality

Answer 5

number of solute molecules in 1kg of solution

Question 6

molarity

Answer 6

amount of solute in 1 litre of solution

Question 7

aqeuous solution

Answer 7

solution where the solvent is water

Question 8

solubility

Answer 8

largest quantity of matter that can be dissolved in a certain amount of solvent

Question 9

raults law

Answer 9

vapor pressure or component in ideal solution is directly proportional to the molar fraction

Question 10

factors affecting solubilty

Answer 10

temperature
nature of solute and solvent
pressure

Question 11

factors that accelerate solubility process

Answer 11

volume of solute particles
stirring and shaking
temprature

Question 12

real solution

Answer 12

a homogeneous solution in which the solute particles have volumes ranging from 0.1nm to 1nm

Question 13

colloidal systems

Answer 13

case between real solutions and plankton, size range 1nm to 100nm

Question 14

plankton

Answer 14

solid particles stuck in liquid medium and therefore they are systems consisting of 2 phases solid and liquid particles size more than 100nm
