Chemistry | Concentration and Dilution

Today we are learning about Concentration and Dilution. Concentration has more particles and dilution has less particles.  

Concentration is a measure of how much solute had been dissolved in to the solvent/how much it has been dissolved into a liquid. 

We can measure in two ways: 
1. How dilute something is (how weak it is)
2. How concentrated something is (how strong it is)

Dilution is when we make something less concentrated. We make things weaker by diluting it. 

Our experiment is making a Dilution Series. 5ml water into 5 of the test tubes and 10ml into one of the test tubes. A dilution series is when we move one of the liquids from one into the other tubes. We will be putting a piece of crystal potassium into one of the test tubes. 
The purple crystal we used was called potassium Permanganate which was the solute. The Solvent was Water. 

What happened:
While we transferred 5ml of the last liquid into the next test tubes, the solution went from concentrated to very diluted. The colour got less and less because it was more dilute. Our solution was the mixture of the crystal and water. The more we took out the liquid from the other test tube it was more dilute because of the more liquid that was in the next test tube. The start of the test tube was concentrated and the end went more dilute.
