Separation Techniques Flashcard

Front

What is Filtration?

Back

Filtration is a separation technique used to separate solid particles from a liquid or gas by passing the mixture through a filter that allows only the liquid or gas to pass through.

What is a Sieve?

Back

A sieve is a tool used to separate larger particles from smaller ones or to separate solids from liquids, commonly used in cooking and construction.

Front

What is the use of a Magnet in separation techniques?

Back

A magnet is used to attract and separate magnetic materials, such as metal scraps, from non-magnetic materials.

Front

What is Distillation?

Back

Distillation is a separation technique that involves heating a liquid to create vapor and then cooling the vapor to create a liquid, used to separate mixtures based on different boiling points.

Front

What is Chromatography?

Back

Chromatography is a technique used to separate mixtures based on the movement of different components through a medium, often used in laboratories to analyze substances.

Front

What is Evaporation?

Back

Evaporation is the process of turning a liquid into vapor, often used to separate a dissolved solid from a liquid by heating.

Front

What is the purpose of Separation Techniques?

Back

Separation techniques are used to isolate specific components from a mixture for analysis, purification, or to obtain desired materials.

Front

What type of mixture can be separated using Filtration?

Back

Filtration is effective for separating mixtures of solids and liquids, such as sand and water.

Front

How can Sand and Gravel be separated?

Back

Sand and gravel can be separated using a sieve, which allows smaller particles to pass through while retaining larger ones.

Front

What is the principle behind using a Magnet for separation?

Back

The principle behind using a magnet for separation is based on the magnetic properties of certain materials, allowing them to be attracted and removed from non-magnetic materials.
