No Reaction
I haven't a clue
The ribbon starts to break up at the surface, a brown solid forms(copper metal), and the solution eventually becomes colourless (from losing copper ions)
Nothing
magnesium sulphate, calcium chloride and ferric chloride are added to provided optimum environment and phosphate buffer is added to slow down the rate of death of microbes.
it fizzes up like poo and wee in ur body when people say ur sexy and ur nipples r great this is said when hydroxide solution is added to copper II sulphate solution
I haven't a clue
The chemical reaction is:Fe + CuSO4 = FeSO4 + Cu
No colour
White precipitate of barium sulphate

Sh!t happens.

I think sodium Hypo chlore is act as a color removal reagent. it is used to develop the sulphate color to white. If any other reasones are there please inform me.

When we did it the other day what happened was this: the magnesium caused tiny bubbles and little dots of black fell to the bottom of the test tube (Copper I guess). When the reaction stopped, the liquid was still blue. We tried heating the mixture and got a bit more bubbles and 'dots' then we left the test tube for several days. Now the magnesium is coated with a pretty turquise coating of something, the solution is still blue, the dots are still black at the bottom of the tube. So CuSO4 + H2O + Mg should give you MgSO4 (which is soluble) and Cu. I do not know what we have actually got. The chemicals came from a chemistry set...the CaOH was equally not 'right' or rather it was far less 'basic' that I expected hmmm.
Sodium sulfate solution is neutral; the red litmus is purple.
