Solutions

Question 1

Mixture is?

Answer 1

2 different substances

Question 2

Can a mixture be separated

Answer 2

Yes

Question 3

Solution

Answer 3

Homogenous mixture with different properties where you cannot differentiate the substances

Question 4

Solvent vs Solute

Answer 4

Solvent does the dissolving (water)

Solute gets dissolved (salt, sugar)

Question 5

Aqueous solution

Answer 5

Solvent is water

Question 6

Solubility

Answer 6

Maximum amount of solute that can be dissolved in a certain volume of solvant

Question 7

Factors that influence solubility

Answer 7

Temperature
Pressure
Nature of the solute
Nature of the solvant

Question 8

Increase of temperature affects solubility of solids and gazes. How so?

Answer 8

Solids get increased solubility

Gazes get decreased solubility

Question 9

Concentration

Answer 9

Quantity of Solute/Quantity of solution

Question 10

Dilution
Dissolution
Evaporation

Answer 10

Adds solvent and decreases concentration

Adds solute and increases concentration

Reduces solvent increases concentration

Question 11

1) G/L
2) %m/v
3) %v/m
4) %m/m
5) ppm
6) mol/l or M

Answer 11

1) X grams per 1 litre
2) x grams per 100 millilitres
3) x millilitres in 100 grams
4) x grams in 100 grams
5) number of parts of solute in 1000000 parts of solution
6) number of moles in 1 litre

Question 12

1 PPM in Grams

1 PPM in L

Answer 12

1g/1000000g = 1mg/1000g= 1mg/kg

1g/1000000ml = 1g/1000L= 1mg/1L

Question 13

Formula fir dilution

Answer 13

C1 X V1=C2 X V2

C1>C2
V2>V1
