Mixtures and Solutions

Front

What are mixtures?

Back

different materials placed together but keeping their own properties

Answer explanation

Mixtures consist of different materials combined together while retaining their individual properties. This distinguishes them from solutions, where substances may dissolve and lose their original characteristics.

Front

What is a solution?

Back

a mixture in which substances spread out evenly and will not settle

Answer explanation

A solution is defined as a mixture where substances are evenly distributed and do not settle, making 'a mixture in which substances spread out evenly and will not settle' the correct choice.

Front

Solubility

Back

the degree to which a material will dissolve in another substance

Answer explanation

Solubility refers to the degree to which a material can dissolve in another substance. The correct choice explains this concept accurately, distinguishing it from other options that describe mixtures or components.

Front

What is a solvent?

Back

the substance in a solution that has the greatest amount

Answer explanation

A solvent is defined as the substance in a solution that has the greatest amount, which allows it to dissolve other substances. This distinguishes it from solutes, which are present in lesser amounts.

Front

Solute

Back

The substance in a solution that has the least amount.

Answer explanation

A solute is defined as the substance in a solution that has the least amount. It dissolves in the solvent, which is the substance present in the greater amount.

Front

Which process would you use to separate and analyze the solutes in a solution, where bands of color form on filter paper to show the different substances?

Back

Chromatography

Answer explanation

The correct process to separate and analyze solutes in a solution is chromatography. This technique allows different substances to form distinct color bands on filter paper, indicating their presence.

Front

Which process would you use to separate magnetic material from a mixture of other substances?

Back

Magnetic Attraction

Answer explanation

To separate magnetic material from a mixture, the best method is Magnetic Attraction. This process uses magnets to pull out magnetic substances, making it effective for this specific task.

Front

Which process would you use to separate solid particles from larger particles in a mixture with filter paper in a funnel to trap solids so that the liquids will pass through?

Back

Filtration

Answer explanation

The correct process to separate solid particles from larger particles in a mixture is filtration. Using filter paper in a funnel allows solids to be trapped while liquids pass through, effectively separating the components.

Front

Which process would you use to separate solids that float from the remaining solids and other items that remain in a liquid mixture?

Back

Floatation

Answer explanation

Floatation is the process used to separate solids that float from a liquid mixture. The solids rise to the surface, allowing them to be skimmed off easily, making it the correct choice for this separation method.

Front

Which process would you use to separate smaller solid particles from larger solid particles using a screen with certain sized holes?

Back

Sifting

Answer explanation

Sifting is the process used to separate smaller solid particles from larger ones by using a screen with holes. The smaller particles pass through while the larger ones remain, making sifting the correct choice.
