Why water cannot be used to prepare sodium thiosulphate solution?
One should use freshly boiled pure water to prevent oxidation by otherwise present oxygen. After complete solvation of the 'hypo' (more familiar known as the pentahydrate, Na2S2O3•5H2O) the solution should be filtered to after standing overnight to remove sparse sulfur sedimentation.
What do you get when mix copper sulphate and chlorine bleach?
I made a copper sulphate solution using 1 heaped tablespoon sulphate and 90ml water, boiled it and let it all dissolve. then took some bleach in a syringe squirted it in and... It went brown/black looking exactly like bird poo and it went like a paste instantly after touching the solution.... try it, it was fun! :D
Does salt water condensate?
No. The reason for this deals with the nature of condensation and solutions. A solution is a liquid where the dominant liquid or solvent has other solids, liquids, or ions, in it called solutes. Saltwater is a solution where water is the solvent and the salts are the solutes. When a solution boils, the solutes and solvents split apart. For example, vodka is a solution where water is a solvent and alcohol is the solute. Since alcohol boils at a lower temperature than water the alcohol boils off before the water does. In the case of saltwater, the water boils long before salt. Condensation is when a gas turns into a liquid. Since the water vapor does not carry salt (i.e. fresh water vapor from boiled saltwater), it does not condense as saltwater but as fresh water.
What size is water vapor?
It depends on the amount of water boiled to make that vapor.
Why does fresh liver react better in H2O2 then boiled liver?
It all has to do with catalase. Catalase is an enzyme and a biological catalyst in the decomposition of H2O2. When its fresh, catalase is still present in the liver. However, when the liver is boiled, the catalase enzyme is denatured (as it is a protein).
