Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution.

Front

What combination would dissolve a solid solute the fastest? high temperature, no stirring; no heat, no stirring; sugar cube, no heat; high temperature, stirring.

Back

High temperature, stirring.

Front

What does insoluble mean?

Back

Unable to dissolve in a solvent.

Front

What is solubility?

Back

Solubility is the ability of a substance to dissolve in a solvent at a given temperature and pressure.

Front

How does temperature affect solubility?

Back

Generally, increasing temperature increases the solubility of solids in liquids.

Front

What is agitation in the context of dissolving?

Back

Agitation refers to stirring or shaking a solution to help dissolve a solute faster.

Front

What is surface area and how does it affect dissolving?

Back

Surface area is the exposed area of a solute; greater surface area allows for faster dissolving.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution.
