Growing Crystals

Aim

I want to find out how to make crystals from a supersaturated solution

Equipment

-A super solution of Sodium Acetate

-A seed crystal of Sodium Acetate

-Bunsen burner

-Boiling Tube

-Test Tube Tongs

-Heat Mat

-Funnel

-Filter Paper

-Small Beaker

Method

-Fold the Filter paper. and put it in the funnel (The teacher will show you)
-Put the funnel on either the Beaker or the Test tube.
-Put in the solution given by the teacher.
- Wait for it until it reacher 2/3 of the Test Tube/Beaker
-Set up the Bunsen Burner
-Heat up the Solution
-Take it in and out
-Once down cool it down with water for 5 minutes
-After that take it and drop a crystal

Results

Discussion

-After boiling my solution and cooling it down, I put some crystal in it exploded into a crystal.

Separating Mixtures

Aim

To separate a solution from a precipitate (precipitate is the name for a solid that forms in a liquid during a chemical reaction)

Equipment

-Lead II nitrate 

-Potassium iodide

-Stirring rod 

-A 10ml beaker

-A funnel 

-Filter paper

Method

1.) Pour approximately 10 ml of Lead II Nitrate into a beaker

2.)Add the same volume of Potassium Iodide. A precipitation reaction will occur, resulting in a cloudy yellow precipitate of Potassium Nitrate

3.)Your science teacher will show you how to fold the filter paper so it fits inside your funnel

4.)Place the funnel, with the filter paper inside it, into the mouth of a conical flask.

5.)Stir, then carefully pour the precipitate mixture into the funnel.

Observation

Outline what you saw happen

When I pour the Potassium Nitrate (mixtures of Lead II Nitrate and Potassium Iodide) it filtered through a clear liquid into the Conical Flask.

Discussion

-When I mix the two chemicals it went cloudy yellow.
-When I filtered the chemicals through the filter paper it prevented the yellow bits to come through.

-A clear liquid filtered through.
