Suspensions vs Solutions

Definitions:

• Suspension: A mixture in which the different particles are easily seen in a liquid or a gas
• Solution: a mixture that appears to be a single substance but is made of particles of two or more substances that are distributed evenly amongst each other.

Part 1: Filtering A Mixture

Procedure:

1. Using a 250 ml beaker, get about 150 ml of the water with the plastic beads.  Make sure to stir before pouring. 

2. Place the filter inside of the funnel.

3. Place the funnel inside the 250 ml Erlenmeyer flask.

4. Pour the Water with plastic beads into the funnel. Write down your observation in the data table.

5. Pour out the filtered water that was in the flask down the sink

6. Take the beads that are left in the filter and pour it in the beaker labeled "Plastic Beads" in the front of the room.  Keep the Filter inside the funnel.  You will need it again.

7. Repeat steps 1 – 4 for the plain water that is set up at the front of the room or at the back of the room. Make sure to keep the filtered water. You will need it for Part 2.

Results:

Data Analysis:

1. What type of mixture is the water with plastic beads, a solution or a suspension mixuture?

Suspension.

2. Looking at the water, could it possibly be a mixture or are you sure it is a pure substance? Why?

it could be a mixtrure because it's 2 part hydrogen and 1 part oxygen

Part 2: Solutions vs. Pure Substance

Procedures:

1. Take the filtered water from part 1 and pour 10 ml into a 100 ml beaker

2. Take the beaker and place it on the hot plate.

3. Turn the hotplate on the highest temperature.

4. When all of the water has been boiled off, turn the hot plate off and have Mr. Ozeni take the beaker off the hot plate.

5. Observe what you see in the beaker and write it in the data table.

Results/Data Table:

Data Analysis:

1. Was the water actually a pure substance or a mixture?  What is your evidence?

It was a mixture. The water evaporated and left a salt looking substance.

2. Were you able to tell if the water was a pure substance or a mixture, prior to boiling off the water?

NO I thought it was just a pure substance. Except that I knew it was part hydrogen and oxygen.

3.  Fill in the table:

Type of Mixture	By appearances, does it look like a mixture?	Can these mixtures be separated?	What method was used to separate these mixtures?
Suspension	Yes	Yes	Filter
Solution	No	Yes	Heat

 

 

Other Notes: (use pages 90-96 in your textbook)

1. Can Mixtures be separated easily?

Some can and be and some can't only suspension can be easily broken apart.

2. When a mixture is made, is something new created with new properties?

Sometimes. If you just put beads into water it is not something with new properties.

3. Find three examples of a pure substance, solutions, and suspension and get an image for each one.

	Suspension	Solution
Example 1:
Example 2:
Example 3:

4. Fill in the table:

Description	Mixture or Pure Substance	If a mixture, Suspension or Solution
You mix salt into water, but you can’t see the salt.	Mixture	solution
Gold is shaped into a bar and when you melt it, nothing gets separated	Pure substance
A baby poops in the bath tub full of water	Mixture	Suspension
You place water that looks like nothing has been mixed with it inside of the freezer. After the water freezes, you notice little chunks of crystals floating.	Mixture	Solution
Liquid lead is frozen and nothing gets separated	Pure substance

Partner 1 Summary	Partner 2 Summary
In today's small lab activity the experiment was to filter plain water bin a 250 ml flask . After that we had to pour 10 ml in a 100ml beaker . The next step after that was to place the beaker in a hot plate and let it sit their until the water started boiling up , the plate was set to 300 degrees  when the water started boiling Mr.Ozeni came to take the beaker off and let it evaporate	In today's lab we used the filter and put water into a 250 ml flask. After pouring 10 ml into the beaker, we put it on the hot plate and set it on the highest temperature. We waited for it to boil and evaporate. The water then left over particles which meant it was a mixture. We learned that there are 2 types of mixtures: suspensions and solutions. This was a solution.

Partner 3 Summary

Partner 4 Summary

During this expirement first we filtered regular and plain water into a 250 ml flask. Then we poured 10ml of it into a 100ml beaker. After that we put it on the hot plate and set it at 300 degrees where the water evaporated. The two types of mixtures are suspensions and solutions. You can tell if a liquid is a pure substance by heating it up and if its the same as it was before it's a pure substance.
