Water and solution : solubility

How many factor affect the rate of solubility?

• 1

• 2

• 3

• 4

It is a maximum amount of solute that is soluble in 100 cm³ of solvent at a specific temperature.

This statement refers to

• Solute

• Solution

• Solubility

• Solvent

Diagram shows a UHT milk. It is example of ...

• Suspension

• Solute

• Colloids

Diagram shows experiment to study the effect if stirring and without stirring salts to its rate of solubility in water. Both beaker contain 100 cm³ of water.

What is the manipulated variable?

• Rate of solubility

• Temperature

• Volume if water

• Stirring and not stirring process

Diagram shows the experiment to study effect of stirring and not stirring salt in water towards its solubility in water. In which beaker does salt dissolves quickly

• A

• B

Why does salt dissolves faster in water if you stir it?

• Solvent and solute particles move faster and allow the solute to fill up empty spaces between solvent particles

• Solvent and solute particles gain more heat energy to move in empty spaces inbetween them

Diagram above shows the solubity between fine and coarse salt.

Which salt dissolves faster?

• Fine salt

• Coarse salt

Why fine salt dissolves faster bin water compared to coarse salt?

• Fine salt has bigger total surface area exposed to water

• Fine salt has smaller total surgace arra exposed to water

In which beaker does salt dissolves faster?

• Hot water

• Room temperature

• Ice watet

Why does salt dissolves faster in hot water?

• Hot water hive high kinetic energy to solvent and solute perticles

• More collision between solute and solvent particles

• Higher temperature gives more surgace area to the solute
