Today you will be a forensic chemist. 

A bag of white powder has been confiscated by the airport customs. You need to find out what white powder it is?

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

There are  a number of different white powders in our everyday life. Some of these are harmful and others are not. Test the four white powders listed to see which one has been found at the airport.

Here are some examples of everyday kitchen white powders.

Flour

Cornflour

Sugar

Salt

Baking Soda

Baking Powder

Icing Sugar

Tartaric Acid

Citric Acid

Gluten Free flour

Materials
1.  sugar
2.  salt
3.  corn flour
4.  baking soda
5.  iodline
6.  vinger
7.  water

Upload a photo of each powder.

 
 


On the black cardboard using a microscope you need to record what you see. You will be given a small amount of 4 white powders on your cardboard. Look at them under your microscope and record what you see. 
Do not mix the powders or taste the powders.

Findings:

	Sugar	Salt	Baking Soda	Cornflour
Appearance	white powder	white powder	white powder	white powder
Texture	rough	rough	smooth	smooth
Smell	sweet	salty	fizzy	thick
Iodine	black	gold	brown	foamed
Water	black	no effect	fizzed	no effect
Vinegar	black	no effect	fizzed	no effect

Write a paragraph about your findings.
I found out that different chemicals  have different reactions like baking soda fizzes with water and vinger and corn flour has no effect with water and vinger all the sugar did was turn black it might be because it went transparent the salt turned gold and then had no effect with the other experiments
