A solution is made up of two components. The first is the solute. What is the solute?

• The substance that dissolves

• The substance that does the dissolving

• The liquid substance

• None of the above

Choose from the options below an example of a solute

• 
• 
• 
• 

A solvent is

• a mixture

• a liquid

• A liquid substance which dissolves a solute

• anything that can mix

Choose from the list below, an example of a solvent

• sand

• sugar

• salt

• water

The ability of a solute to be dissolved is called its

• nature

• mixture

• solubility

• solvent

Solute + Solvent =

• Mixture

• colloid

• suspension

• solution

Select all the factors which can affect the solubility of a substance

• temperature

• size of solute or the surface area of the solute

• the amount of stirring

• colour of the solute

Select ALL the correct statement from the options below

• The hotter the water, the slower the salt will dissolve

• The hotter the water, the faster the salt will dissolve

• The smaller the size of the salt particles, the faster they will dissolve

• The larger the salt particles, the faster they will dissolve

What factor affects the solubility of a solute in a given solvent?

• Temperature

• Pressure

• Volume

• Density

What effect does increasing temperature have on the solubility of most solid solutes in a solvent?

• Decreases solubility

• Increases solubility

• No effect on solubility

• Forms a precipitate
