EXPERIMENT 1
---------------
Titanium dissolves in dilute hydrochloric acid with great difficulty. When
hydrofluoric acid is present as well, then the metal dissolves easily. A
tinanium (III) fluoro complex is formed.
EXPERIMENT 2
---------------
Titanium slowly dissolves in concentrated hydrochloric acid, forming deep
blue/violet titanium (III) ions. On addition of hydrogen peroxide these are
oxidized to titanium (IV), which in turn forms a deep red coordination
complex with hydrogen peroxide.
The deep red coordination complex is only stable in acidic to neutral media.
It also is easily reduced by nitrite. It is not affected strongly by
persulfate. With fluoride, a light yellow compound is formed, but the
formation of that may also be due to rise of pH.
EXPERIMENT 3
---------------
Lithium fluoride is only sparingly soluble.
EXPERIMENT 4
---------------
Praseodymium (III) ions form complexes with chloride, bromide and iodide. With
fluoride a precipitate is formed.
EXPERIMENT 5
---------------
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 6
---------------
Nitrite ion is very unstable in concentrated hydrofluoric acid. Although the
acid only is a weak acid, it forces complete decomposition of the nitrite ion
and potassium fluoride remains behind in solution.
