My 80%w/v sucrose solution seems to have some floaties in it. What are they?
There are two types of 'floaties' you may seen in this solution. The first is will be white or translucent. As this is a fully Saturated solution, a few particle will fall out of solution. The second type, if present, will be darker in colour. These are impurities in the sucrose that do not disolve in the solution. They will not effect the outcome of the experiment.
Why can’t I see my rainbow?
There are a few possibilities for this. If the coloured solutions mix in the cup you won’t see it. This can happen when the layers are added fast or it can happen if solution is accidently sucked up into the pipette.
Are you looking at the side of the cup. Even looking at a bit of an angle can visually mix the colours and make it harder to see. You’ll notice the pictures of This experiment are all taken straight on.
