Question 1

What is a mixture

Answer 1

A group of two or more elements that are not chemically combined

Question 2

What is a solvent

Answer 2

A subtance that dissolves multiple soluble subtances

Question 3

What are soluble and insoluble substnaces

Answer 3

Soluble can disolve
Insoluble cannot

Question 4

What are the ways to seperate mixtures

Answer 4

Paper chromotography
Filtration
Evaporation
Crystillation
Distillation
Fractional distilation

Question 5

Get paper

Explain chromotography and go step by step

Answer 5

Used to seperate substances in a mixture
Draw line near bottom of filter paper Use pencil
Add a spot of ink on the line
Place the sheet into a beaker filled with a solvent like water depending on mixture used
Beaker should be place with 2 cm of solvet
The solvent seeps up the filter paper
When the solvent has nearly reached top of paper take it out
Leave it to dry and those are your results

Question 6

Explain Filtration and the steps

Answer 6

Filtration seperates insoluble solids from liquids
Liquid is poured through the filter paper into a funnel.
The liquid that comes through is pure

Question 7

Explain evaporation and the steps

Answer 7

Pour the solution into an evaporating basin
Slowly heat the basin
You will be left with crystals

Question 8

Explain crystillisation and the step by step

Answer 8

Same as evaporation but when half of solvent is gone then take of the heat and leave to rest

Question 9

Disti
