Results for 'sodium fluoride':
EXPERIMENT 1
---------------
Iron does not dissolve quickly in dilute hydrochloric acid. When some sodium
fluoride is added, then it still does not dissolve quickly. This is in strong
contrast with titanium metal, which does dissolve quickly in dilute HCl,
when some HF is present.
EXPERIMENT 2
---------------
Praseodymium (III) ions form complexes with chloride, bromide and iodide. With
fluoride a precipitate is formed.
EXPERIMENT 3
---------------
Lithium fluoride is only sparingly soluble.
EXPERIMENT 4
---------------
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 5
---------------
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.
