Hey guys! The thing is i just finished making footage about germane, where the main precursor
was germanium tetrachloride and before I upload it to the channel in few days i'd like to
show you a couple of reactions with germanium tetrachloride by the way that reaction in the
community tab is a reaction of germane with silver nitrate solution nobody guessed the reaction
germanium tetrachloride represents a colorless caustic liquid unlike other liquid tetrachlorides
such as vanadium titanium silicon and tin germanium tetrachloride fumes much more weakly
in humid atmosphere this chemical is the result of heating elemental germanium and chlorine flow
i didn't drain chlorine for this reaction so
that it would be possible to see germanium tetrachloride forming
see that white smoke that's forming in the reaction area? that's the vapors
of germanium tetrachloride that react with the moisture of air forming white germanium dioxide
and this is what will happen if we add liquid chlorine to heated germanium
Adding germanium tetrachloride in water causes its hydrolysis
with the formation of germanium dioxide well to be more precise it's not an oxide that's forming,
but a hydrated oxide and it gets calcinated in order to get pure germanium dioxide
germanium dioxide is an amphoteric oxide it is
easily soluble in a concentrated alkali solution with the formation of potassium
hexahydroxygerminate
potassium iodide is very sensitive to germanium tetrachloride vapors
you can see potassium iodide turn yellow even before it touches a drop of the
reagent this is a reaction with the formation of another germanium halide that is tetraiodide
germanium tetraiodite represents an orange-brown powder
when heated it decomposes into iodine and germanium diiodide
Colorless tin (II) chloride crystals slowly turn it into
germanium tetrachloride even at room temperature
when heated at a temperature above 80 degrees celsius concentrated sulfuric acid is able to
oxidize germanium tetraiodide to elemental iodine I could not find a reaction equation
describing this process so try to write the equation for this reaction in the comments
and a very interesting reaction with germanium tetrachloride occurs
when it interacts with lithium aluminum hydride in dry diethyl ether
we'll take a closer look at this reaction in the next video so don't forget to subscribe to
