Results for 'ligroin':
EXPERIMENT 1
---------------
Permanganate is a strong (and dangerous) oxidizer, when combined with
concentrated sulphuric acid. It is capable of lighting paper and acetone,
without the use of matches.
Permanganate, mixed with a mixture of nitric acid and sulphuric acid is
a strong oxidizer as well, but not as powerful as when mixed with
sulphuric acid only.
EXPERIMENT 2
---------------
Alkanes do not react strongly with NO2. Some NO2 dissolves in them.
EXPERIMENT 3
---------------
Nitrogen oxides do not dissolve in ligroin. Nitrosyl bromide does. When a
compound with unstaturated C=C bonds is added, then the nitrosyl bromide
does not quickly decompose. It does not react with alkenes and the presence
of alkenes does not cause it to decompose quickly.
EXPERIMENT 4
---------------
Cobalt chloride, both the anhydrous form and the hydrated form (with 6 H2O)
dissolve in acetone, giving a deep blue/cyan solution. When an apolar solvent
is added to this (e.g. ligroin), then the solution of anhydrous cobalt chloride
gives a fine light blue precipitate, the solution of the hydrated cobalt
chloride gives small droplets of deep cyan/blue solution, with a colorless
liquid above it.
EXPERIMENT 5
---------------
Sodium selenite dissolves in concentrated hydrobromic acid with a red/brown
color. When this solution is shaken with ligroin, then the ligroin layer also
turns red/brown. The compound, dissolved in the ligroin layer is a selenium
compound, as is demonstrated by the experiment, described in more detail below.
