Unit 1: Solutions

Front

What is a solution?

Back

A solution is a kind of mixture where one substance (solute) is dissolved in another (solvent).

Front

What is the universal solvent?

Back

Water is known as the universal solvent because it can dissolve more substances than any other liquid.

Crystals can form when liquids cool and start to harden, when magma cools, or when water evaporates from a mixture.

Front

What is a control group in an experiment?

Back

A control group is a variable that does not change during an experiment, used for comparison.

Front

What is the difference between a mixture and a compound?

Back

A mixture is a combination of two or more substances that retain their individual properties, while a compound is a substance formed when two or more elements chemically bond.

Front

What happens when a solute is added to a solvent?

Back

When a solute is added to a solvent, it dissolves, resulting in a homogeneous mixture called a solution.

Front

What is saturation in a solution?

Back

Saturation occurs when a solution can no longer dissolve additional solute at a given temperature and pressure.

Front

What is the process of dissolving?

Back

Dissolving is the process where solute particles are surrounded by solvent molecules and separated from each other.
