Question 1 of 10
What is a saturated solution? A saturated solution is a:
 


diluted solution.


solution that can't dissolve additional quantities of solute.


heterogeneous mixture.


solution that can dissolve additional quantities of solute.
Question 2 of 10
Choose the correct statement:
 


A 100 ml water can dissolve any quantity of sugar.


A given volume of solvent dissolve any quantity of solute.


Any quantity of sugar can be dissolved in 100ml water.


A given quantity of sugar can be dissolved in 100ml water.
Question 3 of 10
Indicate which of the following does not affect the solubility of solid solutes.
 


Temperature.


Stirring.


Quantity of solute.


Volume of solvent.
Question 4 of 10
Choose the correct statement:
 


Grinding solids decreases their surface area of contact.


Heating slows down (decreases) rate of dissolution.


Stirring slows down (decreases) rate of dissolution.


Grinding solids speeds up their rate of dissolution.
Question 5 of 10
The solubility of solids depends on temperature. As temperature increases,
 


the solubility of most solid solutes drops to zero.


the solubility of most solid solutes decreases.


the solubility of most solid solutes does not vary.


the solubility of most solid solutes increases.
Question 6 of 10
How does the solubility of sugar vary with temperature?
 


As temperature increases,solubility of sugar doesn't vary.


As temperature increases, solubility of sugar increases.


As temperature increases,solubility of sugar drops to zero


As temperature decreases, solubility of sugar increases.
Question 7 of 10
The solubility of gases depends on temperature and pressure.
 


An increase in pressure, decreases solubility of gases.


An increase in pressure, increases solubility of gases.


An increase in temperature, increases solubility of gases.


An increase in temperature,doesn't affect solubility of gas
Question 8 of 10
Keep carbonated drinks in cold places,
 


does not affect solubility of carbon dixoide gas in water.


decreases solubility of carbon dixoide gas in water.


increases solubility of sugar in water.


increases solubility of carbon dixoide gas in water.
Question 9 of 10
When someone opens a bottle of carbonated drinks, the pressure inside the bottle decreases. This results in:
 


an increase in the solubility of sugar in water.


a decrease in the solubility of CO2 gas in water.


an increase in the solubility of CO2 gas in water.


a no change in the solubility of CO2 gas in water.
Question 10 of 10
Fish need oxygen to survive. Goldfish in a crowded aquarium have a better chance of survival in cold water than in warm water because:
 


In cold water,solubility of oxygen gas decreases.


In cold water,solubility of oxygen gas increases.


In warm water,solubility of oxygen gas increases.


In warm water,solubility of salts increases.
