Hello, today in science class we are learning about concentration and dilute.
Concentration is a measure of how solute has been dissolved into the solvent.
We can measure in two ways:
- How dilute something is...(how weak it is)
- How concentrated something is...(how strong it is)
Dilution means making something less concentrated.
Today experiment we are doing is a Serial Dilution.
Aim: Carry ut a Serial Dilution with Potassium Permanganate.
Hypothesis: I think it will turn purple when we add it with water.
Observation: When I add the Potassium Permanganate the water turns purple and as I add the liquid with thethe liquid became less and less purple.
Discussion: the First test tube has more Potassium Permanganate so its purple and the sixth test tube has less Potassium Permanganate so its colour less with a tint of purple.
