Dilution Experiment 

Aim
I want to investigate how to dilute a solution.

What is dilution
Something that mix with water like for example there a bottle of coke for example there's 10% in coke and 9% off water there no dilution cause there more coke the clear water.

Equipment

• 5 test tube 
• 10ml of water in one of the test tube 
• 9ml in the other test tube 
• potassium permanganate
• string rod 

Results
 it was fun when we put the potassium permanganate a  crystal in each tube it went pretty good to be honest everything went good until we spelt some.

But everything went okay with the experiment.

And a photo as well.

Conclusion

Me and my group went to get 10ml in one off the tubes and the rest 9ml we put potassium permanganate the colour at first was a dark purple colour. Then we put a little bit of the potassium permanganate in the other tubes and we stirred it and it become lighter and lighter until it's clear.but some might not come clear.
