Science: Concentration and dilution

Concentration and dilution 

01/06

Today in science we learning about Concentration and dilution.

Concentration: A measure of how much solute(something) has been dissolved into the liquid solvent.

(In other words how much solute there is in the solution)

We can measure in two ways:

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

-How concentrated something.(How strong it is).

dilution: Is when we make something less concentrated(weaker). 

There will be less particles in the liquid.

Solute: Potassium Permanganate

Solvent: Water

Observation and discussion: After putting the Potassium Permanganate crystal into the first test tube which had water in it, the liquid in the test tube became a dark purple colour. Each time we added 5 ml to the next test tube from the one before the liquid became more dilute (meaning the liquid became more weaker).
