dituions from a dissolved crystal







  • the first thing we did was we placed six test tubes in the test tube rack. labels the rack with numbers using a measuring cylinder fill test tube 1 with 10 ml. of water using your tweezers add a single crystal of gently shake the first tube until the crystal dissolved. using the transfernn pipette thoroughly to ensure that no purple solution remains. gently shake test tube 2 test tube 3. rinsh the pipette again and repeat the transfer process for test tubes 4,5 and 6 
the first thing wehad to do is fill the tubes up to 5 high then we go fill the beacker 10 ml high after that we went and got a crystal and dropit into the beacker then we shake it until the colour turns pink then we pour it into the testtube one by one we toke 3 out of the first one and put it into the senonced one then we take out 2 and put it into the 2 one again then we do that for all the others after you can see the colour charging then you take a photo then put it into your blog post then you are done with the expersiment.
