Saturated Solution

• We made a salt solution by dissolving 5cc of salt
  in 50 ml. of water.
• What do you think would happen if we put two
  spoons of salt in 50 ml. of water?

• What do you think would happen if we put two
  spoons of salt in 50 ml. of water?
• Would it dissolve to make a solution?

• What do you think would happen if we put two
  spoons of salt in 50 ml. of water?
• Would it dissolve to make a solution?
• How about three spoons?

How can we find out what might happen if you keep
adding salt to 50 ml. of water?

Saturated Solution

• Question How much salt will dissolve in 50 ml.
  of water?
• To Do
• Measure 50 ml. of water into bottle.
• Put a post-it note on bottle where level of water
  is. Then place bottle under filter stand.
• Measure 5 cc (one at a time) of salt into bottle.
  Then shake.
• 4. Then add another 5 cc of salt and shake until
  the salt does not dissolve.
• 5. Record how many 5cc you put into the bottle.

Saturated Solution

• What happened to the salt when you put it in the
  water?

9
Saturated Solution

• What happened to the salt when you put it in the
  water?
• Where is the salt now?

10
Saturated Solution

• What happened to the salt when you put it in the
  water?
• Where is the salt now?
• What happened to the level of the liquid?

11
Saturated Solution

• What happened to the salt when you put it in the
  water?
• Where is the salt now?
• What happened to the level of the liquid?
• Why did the level go up?

12
Saturated Solution

• You made a solution by dissolving solid
  material in a liquid. In this case the solution
  was salt dissolved in water.

13
Key Concept

• When solid material is added to a solution until
  no more will dissolve, the solution is a
  saturated solution.

Questions

• How do you know you have a saturated salt
  solution?

15
Questions

• How much salt did it take to saturate 50 ml. of
  water?

16
Questions

• What we really need to know is, how many grams of
  salt does it take to saturate 50 ml. of water?

17
Questions

• What we really need to know is, how many grams of
  salt does it take to saturate 50 ml. of water?
• In other words, how many grams of salt are
  dissolved in your saturated solution?

18
Questions

• Is the undissolved salt at the bottom of the
  bottle part of the saturated solution?

19
Questions

• Is the undissolved salt at the bottom of the
  bottle part of the saturated solution?
• What is the mass of 50 ml. of water?

20

• To Do
• Place a labeled cup under the funnel.

21

• To Do
• Place a labeled cup under the funnel.
• Filter the solution using filter paper. The
  saturated solution will pass through the filter
  the undissolved salt wont

22

• To Do
• Place a labeled cup under the funnel.
• Filter the solution using filter paper. The
  saturated solution will pass through the filter
  the undissolved salt wont
• Place the saturated salt solution on one side of
  the balance and 50 ml. of plain water on the
  other side.

23

• To Do
• Place a labeled cup under the funnel.
• Filter the solution using filter paper. The
  saturated solution will pass through the filter
  the undissolved salt wont
• Place the saturated salt solution on one side of
  the balance and 50 ml. of plain water on the
  other side.
• Add gram weights to the plain water to achieve
  balance.

Definitions

• Solvent is the liquid (in this case) into which
  the solid material goes
• Solute the material that dissolves

27
Key Concept

• A solution is always made of a solvent with
  some kind of solute dissolved in it.
