Making A Dilution - Potassium Permonganate Crystal Experiments

Making A Dilution - Potassium Permanganate Crystal Experiments

Equipment - 

Potassium Permanganate Crystal

Six test tubes

Test tube rack

Tweezers

Pipette (5ml)

Measuring Cylinder (10ml)

Water

Method - 

Place 6 test tubes in a test tube rack & label them 1-6.

For the first test tube measure 10ml using a pipette and measuring cylinder(measure from the meniscus) Transfer the water from the measuring cylinder into the first test tube. Fill the remaining test tubes with 5mls instead of 10ml.

Using your tweezers add a small Potassium Permanganate crystal into the test tube with the most water (1oml) and shake around without spilling until it has dissolved.

Using the pipette transfer 5mls from the first test tube into the second test tube and repeat for the remaining )one test to to the other).

Results - 

Depending if there where no chemicals mixed during the processed you should end up with a ombre affect or dark to light (dark being 1 light being 6)

Diluting - 

This is called diluting, diluting means to add more solvent until there is less solute of what there was when you first started. There is less of something than the other in the mixture. (Opposite of a Concentration)

Concentrating -  

Concentration is what the solution started off as because there was much more solute than at the end when there was more solvent. There is more of something than the other in a mixture.

(opposite of a Dilution)

Here is our experiment (sorry for the dirty test tubes)
