Doing forensic chemist in science.

What is that white powder?

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

You will be given a small amount of 4 white powders on your cardboard. On the black cardboard using a magnifying glass look at the powders.

Look at them under your magnifying glass and record what you see. 

These are the four powders we will be using. Upload a photo of each powder. 

1.  Cornflour
2.  Baking Soda
3.  Salt
4.  Sugar 
 Before you add the iodine, vinegar or water you will need to divide each powder into 3.

Materials

1.  Cornflour

2.  Baking Soda

3.  Salt

4.  Suger

5.  spoon

6.  paper

7. pencil

Steps

1. First you need some Cornflour ,Baking Soda,Salt,Suger and a spoon a piece of paper and a pencil.

2. Next you need to fold the paper into fours then use the pencil to draw the lines on.

3. Ones you have draw the lines on the paper you can put the Baking Soda in one of the boxes then put the Cornflour in the other one next put the Sugar in the second to last one then in the last box you can put the Salt and then you can put them into three group's.

4. Then ones that is done you can see what it looks like and the texture of it and the smell of it but when you get to put the idine on and the wateron and the vingar on you must put them on separate ones.

5. The next one you can do is what happens if you put lodine on Baking Soda,Suger,Salt,Cornflour.

6. The next two that you can do is to see what happens if you put water and vinegar on them to see what happons to them.

Findings:

	Sugar	Salt	Baking Soda	Cornflour
Appearance	white	white	white	white
Texture	cuby	crumbly	soft/crumbly	soft
Smell	sweet	salty	cooked	has no smell
Iodine	fizzing	crystal	fluffy	no reaction
Water	crystal	crystal	dissolved	oblack
Vinegar	grey	crystal	fizzy	no reaction

Write a paragraph about your findings.

 I was in a group with Kya,Sahara.The first one me and my group did was the sugar the appearance was white the texture was cuby. Then the next one was what it smelled like and that was sweet and then we have to fine out what would happened when we put lodine,water or vinegar. The first one we did was lodine the reaction it hade was just to go fizzing then we put some water on it the reaction it hade was to just crystal.The final one we did with the suger was what would happen if we put some vinegar on it and it just want grey.The next one we did was Salt  bthe appearance was white same as the Suger the texture was crumbly for that one next was what it smell like it smelled very salty then we did what would happen if you got smoe lodine and put it in the salt it just crystal then we did Water and vinegar they were the same as the lodine they crystal.Next we did Baking Soda the appearance of it was white the same as the Salt and Suger one the texture of it was soft/crumbly the next one we did with Baking Soda was what it smelled like the smell of it was cooked then we did what would happon if we put lodine and it went fluffy then was the water the Baking Soda just dissolved it. Then was vinegar the Baking Soda went fizzy.The next one we did was Cornflour the first one was the appearance was white then was the texture it was soft next was what it smell but it had no smell to it then we did lodine but that had no reaction next was water the reaction was it turned to obleck then we did vinegar but like the other one it had no reaction to it.

Conclusion

The very first one we did was the sugar one we had to see what the appearance was and what the texture was and the small then we wanted to see what many different liquids would do to the sugar the first liquid we did was Iodine and it just went fizzing ever where next one we did was water and it just crystal then we did vingar and it did the same as the water one. The next one we did was Baking Soda the appearance of it was white and the texture was soft/crumbly the next one was the small it smelled cooked the next one we did was lodine and it went all fluffy and we did was water and it just dissolved then we did was vingar and it went all fizzy.Then we did Cornflour the appearance was white just like all the others next was texture and it was soft then was the small and it had no small so the next one was the liquids the first one is Iodine and it had no reaction so next was water and it turned to oblack the next one is vingar and well it had no reaction.
So that is it goodbye from me thank you for reading my blog
