7.6 D&E Flashcard Review

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solution. In a saltwater solution, NaCl (salt) is the solute.

Front

What does agitation mean in the context of solutions?

Back

Agitation refers to the act of stirring, shaking, or disturbing a solution to help dissolve a solute more quickly.

Front

How can stirring affect the dissolution of sugar in tea?

Back

Stirring the hot tea helps to dissolve the sugar cube more quickly by increasing agitation.

Front

What is the effect of surface area on the rate of dissolution?

Back

A higher surface area (more little pieces) dissolves faster than a lower surface area (more big pieces).

Front

Which factor does NOT affect the rate of dissolution of a solid solute?

Back

The color of the solute does NOT affect the rate of dissolution.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, forming a solution. In saltwater, water is the solvent.

Front

Define solubility.

Back

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

Front

What happens to the rate of dissolution when temperature increases?

Back

Generally, the rate of dissolution increases with higher temperatures.

Front

What is the relationship between agitation and the rate of dissolution?

Back

Increased agitation typically increases the rate of dissolution by helping to disperse the solute more evenly.

Front

How does the size of solute particles affect dissolution?

Back

Smaller solute particles have a larger surface area, which allows them to dissolve faster than larger particles.
