Results for 'potassium hydroxide':
EXPERIMENT 1
---------------
Cobalt carbonate does not dissolve completely in dilute mineral acids. With
some heating, however, it does dissolve completely.
With nitrite a yellow/orange complex is formed, which forms a precipitate
when treated with alkalies. The precipitate is resistant to treatment with
acid and bases.
EXPERIMENT 2
---------------
Cobalt (II) gives a blue precipitate with hydroxide, but this precipitate
quickly turns pink / purple / light brown after its formation.
EXPERIMENT 3
---------------
Acetone and chloroform react with each other in strongly alkaline
environments, building a compound, called chloretone or chlorbutol.
Formal name of the compound is 1,1,1-trichloro 2-methyl 2-propanol,
formula CCl3 C(CH3)(OH) CH3.
A similar reaction is observed, when MEK is used instead of acetone,
but the reaction is much less vigorous.
EXPERIMENT 4
---------------
Trichloro ethene reacts with acetone, forming a brown substance, but only
when in a strongly alkaline environment. The exact conditions, under which
this brown substance is formed must be further investigated.
EXPERIMENT 5
---------------
Copper hydroxide is decomposed upon heating and loses water, even if
it is surrounded by water.
EXPERIMENT 6
---------------
Oxalic acid does not seem to form a coordination complex with vanadyl ions,
or if a complex is formed, then it has a color, which is almost the same of
the color of aquated vanadyl.
EXPERIMENT 7
---------------
From ice cold strongly alkaline solutions of potassium chromate, one can
create peroxochromate by adding hydrogen peroxide carefully.
EXPERIMENT 8
---------------
This experiment nicely demonstrates the effect of light on a chemical compound.
An alkaline solution of potassium fericyanide (K3Fe(CN)6) is stable in the
dark, but in sunlight it decomposes in a few hours.
