Separating Solids from Liquids

What is the process called when insoluble solids are separated from liquids?

• Filtration

• Evaporation

• Crystallization

• Thermal decomposition

What is the term for a mixture between a liquid and an insoluble solid?

• Solution

• Solute

• Solvent

• Suspension

What is the term for a liquid and a soluble solid?

• Solution

• Solute

• Solvent

• Suspension

What is the purpose of using filter paper in filtration?

• To dissolve the solid

• To evaporate the liquid

• To separate the solid from the liquid

• To heat the mixture

Which technique is used to separate a soluble solid from a liquid?

• Filtration

• Evaporation

• Crystallization

• Thermal decomposition

What happens during evaporation?

• Solvent evaporates and solid remains

• Solid evaporates and solvent remains

• Both solvent and solid evaporate

• Neither solvent nor solid evaporate

Why is crystallization used instead of evaporation for solids susceptible to thermal decomposition?

• Crystallization is faster

• Crystallization prevents thermal decomposition

• Evaporation breaks down the solid

• Evaporation is too slow

What is the first step in crystallization?

• Heating the solution

• Filtering the crystals

• Cooling the solution

• Drying the crystals

Why do crystals form when the solution cools?

• Solids become more soluble at colder temperatures

• Solids become less soluble at colder temperatures

• Solids dissolve in the solution

• Solids evaporate from the solution
