WorksheetsUnit.1. Separating Mixtures
Total questions: 19
Worksheet time: 19mins
This technique separates liquids based differences in the boiling points.
decantation
distillation
filtration
chromatography
This method is used in separating soluble solid from a liquid such as salt from water. In this technique, we don't usually try to collect the liquid; just the solid.
evaporation
distillation
decantation
filtration
Name the separation technique shown in the diagram.
evaporation
distillation
filtration
Apple claims they have made a new ink that can portray more vivid colors than every before. What technique could you use to determine how many pigments the ink is made of.
crystallization
sublimation
chromatography
sedimentation
To separate a mixture of soil and water what separation method is used? (helpful information: soil is not soluble in water)
Filtration
Distillation
Chromatography
Evaporation
What technique will allow you to obtain salt from a mixture of salt water?
Filtration
Distillation
Chromatography
Evaporation
Salt can be separated from sand by adding water to the mixture to dissolve the salt. The separation then takes place in two stages:
evaporation followed by filtration
distillation followed by decanting
filtration followed by evaporation
filtration followed by decanting
In a coffee machine, the ground coffee is separated from the coffee solution by using..
distillation
filtration
evaporation
chromatography
A solution of salt and water was put over heat. What will happen next?
The salt will evaporate
the salt and water evaporate
the water will evaporate
What type of mixture is in the container?
heterogeneous
homogeneous
What type of mixture is coffee?
heterogeneous
homogeneous
What technique is being carried out in the picture?
crystallization
sublimation
chromatography
sedimentation
What technique will allow you to obtain BOTH pure salt and pure water from a mixture of salt water?
Filtration
Distillation
Chromatography
Evaporation
This technique separates and collects liquids that have very similar boiling points.
simple distillation
fractional distillation
evaporation
chromatography
A solution of sand, salt, and stearic acid are mixed with water. Only the salt dissolves. After the mixture is poured through the filter paper, where can the salt be found?
A
B
not enough information
A solution of sand, salt, and stearic acid are mixed with water. Only the salt dissolves. After the mixture is poured through the filter paper, what technique is needed to obtain the salt (the water does not need to be collected)?
filtration again
simple distillation
chromatography
evaporation
