On Monday i was doing an experiment to make the water with potassium permanganate lighter i was dilutioning the water.

Aim : Was to start with a darker color to  make it lighter. 

Method: Place 6 test tubes in to a test tube rack. then in our first test tube we put 10ml in the rest of the test tubes were 5ml.  In the first tube we got tweezers then added a single crystal of potassium permanganate. we mixed it  we took out 5ml we repeated this step till we filled all the test tubes. 

Equipment: test tubes,test tube rack , tweezers
