Results for 'potassium chlorate':
EXPERIMENT 1 --------------- In concentrated phosphoric acid, manganese (II) ions are oxidized easily to manganese (III) ions, which are stabilized by formation of a phosphato-complex with a remarkably bright purple color. This reaction is remarkable in the sense that oxidation stops at manganese (III).
EXPERIMENT 2 --------------- Ethanol and acetic acid do not form an ester (ethylacetate) when simply mixed with concentrated sulphuric acid. More extreme conditions are needed for this reaction to occur. The acid is diluted too much in order to give a strong reaction with chlorate, combined with the reducing agent in the form of ethanol.
EXPERIMENT 3 --------------- Silver (I) forms a precipitate with bromates, while it does not do so with chlorates.
EXPERIMENT 4 --------------- Potassium chlorate is able to liberate bromine from a bromide. Reaction with sodium sulfide of the bromine shows formation of fumes/smoke.
EXPERIMENT 5 --------------- Potassium chlorate only reacts slowly with iodide at room temperature. When heated, the reaction proceeds much faster. Probably KClO3 oxidizes iodine further, until iodate is formed.
EXPERIMENT 6 --------------- When potassium chlorate and concentrated sulphuric acid are mixed, a very dangerous and strong oxidizer is created, which reacts explosively with organic matter.
EXPERIMENT 7 --------------- Although the redox potential from bromate to bromine is higher than the potential from perchlorate to chlorate, when chlorate and bromate are mixed, then no reaction occurs. When some hydrochloric acid is added, then a reaction occurs with the chloride ions.
EXPERIMENT 8 --------------- Chlorate and bromate react with hydrochloric acid, but bromate reacts more vigorously. There also is a marked difference between potassium and sodium chlorate. The sodium salt reacts more vigorous with hydrochloric acid, but not as vigorous as potassium bromate. Reactions of bromate are faster than reactions of chlorate, but for sodium and potassium chlorate, the difference can be explained by the speed at which the salt dissolves.
EXPERIMENT 9 --------------- A mixture of chlorine and chlorine dioxide oxidizes bromide quickly to bromine. When an excess amount of nitrite is added, then the bromine is quickly reduced again to bromide. Addition of an acid does not result in formation of bromine again.
EXPERIMENT 10 --------------- Bromates are more reactive than chlorates in dilute aqueous solutions.
EXPERIMENT 11 --------------- Potassium chlorate and sulphur form a potentially explosive mixture, which is quite sensitive to shock.
EXPERIMENT 12 --------------- Formic acid acts as a reductor, while acetic acid does not do so. Formic acid, however, is not that easily reduced. Reduction requires elevated temperature and strong oxidizers.
EXPERIMENT 13 --------------- Hydrofluoric acid (48% by weight) dissolves potassium chlorate and potassium bromate much more easily than water. The bromate also slowly decomposes in a peculiar way, which is not observed in other acidic solutions (like sulphuric or nitric acids).
EXPERIMENT 14 --------------- Sodium hypophosphite is remarkably flammable. A mix with potassium chlorate is dangerously explosive and can easily be ignited.
