Results for 'K':
EXPERIMENT 1
---------------
Potassium perchlorate is only marginally soluble in cold water, while being
much more soluble in hot water. From perchloric acid solutions, one can easily
precipitate KClO4, almost quantitatively. It is funny to see how a potassium
salt precipitates so quickly and densely.
EXPERIMENT 2
---------------
Cesium alums seem to be nearly insoluble compounds.
EXPERIMENT 3
---------------
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 4
---------------
Thallium(I) metaperiodate is very much like potassium metaperiodate, but it
decomposes easily due to an internal redox reaction in which thallium(III) is
formed, which forms a precipitate with periodate ion.
EXPERIMENT 5
---------------
Sulphur and Carbon are mixed,
Potassium Nitrate is dissolved in hot water and the Sulphur/Carbon mix is
added.
Pure Isopropanol is added, and dehydrates the water, allowing the KNO3 and S/C
to mix closely.
The wet powder is filtered via a vacuum filter, and is dried using ambient
heat.
This produces fast-burning gunpowder.
