Dilution Experiment

 Definition of Dilution: Making something less concentrated

Hypothesis: I think the last tube will be the most diluted due to each time the solution keeps getting passed on and mixed, it loses concentration. The least diluted would be the first tube because its the first one which has had the solution mixed first and had the most of the chemical put into it.

Method:

1. We had to get 10mL in the first tube

2. 5mL in the rest, the 5 tubes

3. Drop a piece of potassium permanganate, the solute in the first tube

4. Use the pipette to draw out 5mL from the tube which has 10mL in at the time and pt the 5mL which you collected and drop into the next tube

5. Repeat till all have been contaminated with the potassium permanganate

6. Inspect result to see which is most concentrated and most diluted

My hypothesis was right because I saw as the first tube which had the solute first be the darkest in colour meaning it was the most concentrated. I then saw the last tube be contaminated be fainter then the first meaning it was diluted the most.

I know that which one is diluted the most since it would be the least dark in colour and the opposite for most concentrated, since if it has more of a dark colour to it then that will mean it will be high in concentration.
