Results for 'sulphur':
EXPERIMENT 1 --------------- Permanganate is a strong (and dangerous) oxidizer, when combined with concentrated sulphuric acid. It is capable of lighting paper and acetone, without the use of matches. Permanganate, mixed with a mixture of nitric acid and sulphuric acid is a strong oxidizer as well, but not as powerful as when mixed with sulphuric acid only.
EXPERIMENT 2 --------------- Acetone can be mixed with water in any ratio, but when sodium hydroxide is added, then the liquids are not miscible in any ratio anymore. Sulphur reacts with acetone in the presence of sodium hydroxide. Sulfide does not show such a reaction.
EXPERIMENT 3 --------------- Sulphur dissolves in a solution of a sulfide. Polysulfides are formed.
EXPERIMENT 4 --------------- Sulphur dissolves in hot solutions of sodium hydroxide and disproportionates in a way, similar to disproportionating of halogens. When acetone is added, a peculiar blue/green compound is formed in the acetone. What is this compound?
EXPERIMENT 5 --------------- Acetone reacts with sulphur in strongly alkaline environments. What products are formed? A similar reaction is observed between methyl ethyl ketone and sulphur.
EXPERIMENT 6 --------------- When potassium bromate and sulphur are mixed, then a very dangerous mixture is created. This mixture, when ignited, produces an intensely bright flame.
EXPERIMENT 7 --------------- A large amount of sulphur can be added to bromine, before a solid remains in the liquid bromine. The sulphur dissolves in the bromine very easily.
EXPERIMENT 8 --------------- Potassium chlorate and sulphur form a potentially explosive mixture, which is quite sensitive to shock.
EXPERIMENT 9 --------------- Chlorite ion forms complexes with cobalt(II) and copper(II). It forms a precipitate with lead(II). The precipitate with lead(II) forms a highly energetic compound.
EXPERIMENT 10 --------------- Sulfide is capable of dissolving sulphur, forming intensely colored poly- sulfide species. These poly-sulphide species react with antimony (III) in strongly acidic environments, resulting in two different types of precipitates.
EXPERIMENT 11 --------------- Antimony sesquioxide does not dissolve in a concentrated solution of NaOH nor does it react with sulfide or one of the polysulfides in strongly alkaline environments.
EXPERIMENT 12 --------------- Potassium bromate reacts with aluminium powder with a very bright light and with crackling noise, but the mix is not like flash powder. Some sulphur is needed for easy ignition of the mix. When a tiny amount of red phosphorus is added to the mix, then it is ignited even more easily, but then it also burns exceptionally fast, almost explosively.
EXPERIMENT 13 --------------- A mix of potassium perchlorate and sulphur cannot easily be ignited. When just a tiny pinch of red phosphorus is mixed in, then the mix is ignited very easily and it burns very fast with a bright flash.
EXPERIMENT 14 --------------- A mix of aluminium powder and potassium permanganate is hard to ignite. When a small amount of sulphur is added, then the mix is easily ignited, and a very bright and fast burning flash is produced.
EXPERIMENT 15 --------------- Sulphur dissolves in carbon disulfide exceedingly easily.
