Degree of Saturation Science 7

You are given a 40mL solution in a beaker. You add solute to the beaker and you observed some particles did not dissolve. What solution is it?

• Saturated

• Unsaturated

• Concentrated

• Supersaturated

What do you call a substance that is dissolved in another substance which is in greater amount?

• Solute

• Solvent

• Solute and Solvent

• Neither Solute nor Solvent

What do you call a substance dissolved in any solution?

• Solute

• Solvent

• Solute & Solvent

• Neither Solute nor Solvent

What you can do if you add more amount of sugar in a cup of hot milk and it taste very sweet?

• Add water

• Add sugar

• Mix the milk solution well

• Put in the refrigerator for an hour

When a solution is saturated?

• Crystals form

• You need to stir it more

• No additional material will dissolve in it

• Two materials have combined to create clear liquid

How will you prepare an unsaturated solution?

• Freeze the mixture

• Stir the powder in the liquid

• Add less amount of powder to the liquid

• Add more amount of solute in a lower amount of solvent

To make a solute dissolve more quickly in a solvent, which would you do?

• Stir it

• Do not stir the solution

• Let the solute settle down

• Nothing to do with the solute

How will you define solubility?

• Lack of polarity of molecules

• Amount of polarity of molecules

• Ability of a solvent to dissolve in a solute

• Ability of a solute to dissolve in a solvent

Which of the following substances is most soluble in water?

• Flour

• Table Salt

• Cooking Oil

• Baking Soda

Which statement is true of any saturated solution at a given temperature?

• No more solute will dissolve in the solution.

• Adding more solute will increase the saturation.

• You can dissolve more solute if you stir the solution.

• One liter of the solution contain 2000 grams of solute.
