White Powder -Home Chemistry

Today in science we are looking at the white powder and forensics. The scenario is there is a bag of white powder has been confiscated by the airport custom. So I need to find out what white powder it is.


Today we will be using a small amount of four white powders in our cardboard. that we have, which is sugar, baking, salt cornflour.

Aim: To learn about the makeup of different white powders.

Materials:

1. Pipettes 

2. magnifying glass 

3. white vinegar 

4. iodine 

5. salt

6. baking soda 

7. cornflour

8. water 

9. black cardboard 

Steps:

1. Get a black cardboard  

2. Fold the black cardboard into four pieces

3. Put the sugar, salt, cornflour and baking soda in the black cardboard

4. Split each of the white powders into thirds

5. Get the iodine put 3 drops each of the white powder 

6. Get the vinegar using pipettes and then put 3 drops each of the white powders 

7. Get the water using pipettes and then put 3 drops each of the white powders 

Findings:

	Sugar	Salt	Baking Soda	Cornflour
Appearance	White	White	White	White
Texture	kinda big grains	small grains	small grains	super small grains
Smell	No smell	no smell	no smell	no smell
Iodine	absorb the sugar	absorb the salt	it melts	hard like gel
Water	absorbs the sugar	nothing happens	it absorbs	hard like oobleck
Vinegar	it absorbs	nothing happens	it bubbles	hard like gel

 Conclusion: 

The white powder that was confiscated in the airport is baking soda. We knew that it was the baking soda when we put the white vinegar on it 'cause it bubbles.

I love this experiment 'cause we need to find out what is the white powder that confiscated in the airport and doing an experiment in sugar, cornflour, baking soda and salt and finding out where in the four is the same thing that confiscated in the airport.
