Back

The substance that is dissolved in a solution.

Front

What is a solvent?

Back

The substance in which the solute is dissolved to form a solution.

Front

What does concentration mean?

Back

The amount of solute present in a given volume of solution.

Front

How does crushing a solid affect its dissolving rate?

Back

Crushing a solid increases its surface area, allowing for more contact with the solvent and speeding up the dissolving process.

Front

Why does temperature affect the dissolving rate?

Back

Higher temperature increases the kinetic energy of molecules, leading to faster dissolving.

Front

What is the best method to separate a mixture of powder and water?

Back

Using a filter is the best method to separate a mixture of powder and water.

Front

What is an example of a solution?

Back

Saltwater is an example of a solution where salt (solute) is dissolved in water (solvent).

Front

What happens to the solubility of most solids as temperature increases?

Back

The solubility of most solids increases as temperature increases.
