100

Which technique is based on the ability of a substance to dissolve into a solvent   

Solubility

100
What is a mixture?
Mixtures are two or more substances that are mixed together but not chemically joined.
100
Give an example of a homogeneous mixture
Peanut butter, ice cream, milk
100

Which technique utilizes a sieve in order to complete separation

Size separation

100

Which separation technique if often used when cooking or baking?

Separation by size (sieving) 

200

Which technique utilizes a property of metals including iron, cobalt and nickel

Separation by magnetism 
200

What is a solute

The smallest component of a mixture

200
Can you take apart a homogeneous mixture? Why?
No, once they are combined the ingredient cannot return the its original state.
200

Which technique uses a special column for separation

Distillation

200
What happens when I combine a solute and a solvent?
You get a solution.
300

Which technique utilizes special paper and ink to perform the separation

Chromatography

300

What is a solvent

The biggest component of a mixture

300
Give an example of a homogeneous mixture that you cannot physically see, but is all around us.
Air.
300

What are three laboratory equipment pieces needed to separate mixtures by magnetism

Magnet, watch glass, scale, porcelain bowl, beaker, filter paper, evaporating dish, crystalizing dish

300

Name the different separation techniques 

Size, magnetism, solubility, distillation, decantation, chromatography 

400

Which technique utilizes immiscible heterogeneous liquids for seperation?

Decantation

400
What does homogeneous mean?
When a mixture does mix evenly-appears too look the same throughout.
400
What two things do you need to create a homogeneous mixture? Be specific.
Solute and Solvent.
400

Which separation technique utilizes a coolant (or condensor)

Distillation

400

What is decantation

Liquids separation of heterogenous mixtures

500

Which technique utilizes boiling point for separation?

Distillation 

500
What is a heterogeneous mixture?
A heterogeneous mixture DOES NOT mix evenly, and you can take it apart.
500
What is the difference between heterogeneous and homogeneous mixture?
Homogeneous looks the same throughout and you can't take the mixture apart. Heterogeneous can be taken apart and is very easy to tell the parts of the mixture.
500

How is a separation funnel used in decantation?

  • Liquid is placed into a separating funnel

  • Open the valve until the desired liquid is almost out of the funnel

  • Some of the mixture is always lost in this process 

500

What is distillation

Separation of a mixture utilizing their differing boiling points
