Concentration and Dilution - Chemistry

 Hello people! Today We will be doing another experiment in this period. 

Also for today's key words we have Concentration and Dilute.

Concentration - A measure of how much solute has been dissolved onto the solvent or in other words, how much solute there is in the solution.

We also can measure it in two ways

- How dilute something is...(how weak it is)

- How Concentrated something is..(how strong it is)

Dilution - Making something less concentrated or there will be less particles in the liquid.

Experiment: Serial Dilution

Aim for today: Cary out (Do) a serial Dilution with potassium Permanganate. 

Hypothesis: For me I think since we have 6 test tubes, one will be more like a dark purple and in process in those last few test tubes the colours will be more lighter. 

Method:

-10ml water in tube 1. 5ml water in the other 5 tubes.

-Use tweezers to put small piece of KMnO4 into tube 1.mix it.

-Use pipette to more 5ml from tube 1 -> tube 2. Mix

 

After Experiment: 

So we have done the Experiment and just like what I expected it came from a dark purple to a very light pick-ish purple.

The first test tube was really concentrated and once we started to put it to another test tube it was becoming more less concentrated than before. We continued on doing that and you can tell that it was becoming more less dilute.
