Serial Dilution!

 AIM - To do a serial dilution.

METHOD - 

1 - Grab 6 test tubes and fill 5 of them with 5ml of water, and 1 tube with 10ml 

2- Add-in potassium permanganate into the tube with 10ml of water. 

3- Move 5ml from test tube one (The one with the potassium permanganate)  into test tube 2 and so on until you get to the last test tube. 

MATERIALS- 

1 - 6 test tubes
2 - Test tube stand 
3 - 35ml of water 
4- Measuring tube 
5 - Dropper thingy 
6 - Potassium Permanganate 

HYPOTHESIS - 

My hypothesis is that the original color of the potassium permanganate (purple) will slowly dilute to almost no colour at all, I think that it will be mostly clear but will have a tint of purple that you can see clearly but isn't as strong as the original colour. 

RESULTS - 

The end result was like a gradient amongst the test tubes, test tube number one being the most concentrated because it had lots of potassium permanganate, and then test tube number  6 being the most diluted, it was almost a clear color with a hint of purple meaning it had hardly any potassium permanganate particles in the diluted solution and had more water particles.
