Solution and Rate of Solubility

Choose the factors affect the rate of solubility :

• Temperature of solvent

• Surrounding temperature

• Rate of stirring

• Size of solute

• Thickness of solvent

A ___________ is the mixture formed when solutes dissolves in a solvent.

• solution

• solvent

• liquid

• solid

Solutes are substances that can ________________ in liquids.

• form

• dissolve

• undissolved

• mixed

Choose the correct characteristics of solution :

• Homogenous

• Does not allow light

• Cloudy

• Uniform colour

• Do not leaves remnants when filtered

If you have a solution with a high concentration of solute, what can you do to increase the amount of solute that dissolves?

• Decrease the temperature

• Add more solvent

• Stop stirring

• Use a smaller container

DOK Level 2: Skill/Concept

The smaller the size of solute, the _________________ the rate of solubility.

• lower

• higher

The _____________ the rate of stirring, the higher the rate of solubility.

• slower

• faster

You can make a solute dissolve more quickly in a solvent by

• adding more solute.

• adding ice.

• heating the solvent.

• removing some solvent.

When you measure how fast a solute dissolves, you are measuring the

• amount of dissolving

• rate of particle movement

• amount of particle movement

• rate of solubility
