1. Place the six test tubes in a test tube rack label them 1-6
2. Using the measuring cylinder fill the test tubes with 10ml (All Of Them) Using the remaining water fill them all with 5ml.
3. Using your tweezers add a single crystal (The smallest one possible) Into the 1st liquid
4. Gently shake the test tube until the crystal has dissolved
5. Using the transfer pipet thoroughly to ensure that you remove almost exactly 5ml and put it into the next one
6. Rinse the parapet to ensure that there is no more purple in it.
7. Gently shake test tube 2 and 1 then repeat this process until the end
8. Rince the pipette again and then to the same againHave Fun
There is a little recount about it
In Science, we have been learning about mixtures. So yesterday we had crystals and put them in water they immediately turned like this purple colour it looked really cool though. Ours was different because it mixed with a leftover chemical in the test tube.
Anyway, The second sample was like a yellow colour it was this the whole way through but the yellow got lighter
Overall I really enjoyed this experiment because it was different from all the other ones but it was
cool.The difference between
Dilution and concentration
Dilution is when it first starts
And concentration is when it' gets mixed with things
