EXPERIMENT 15 ANILINE Flashcards
is a colorless liquid when freshly prepared but changes overtime to dark brown or red?
Aniline
if aniline is oxidized what color does it make?
red or brown
what odor does the aniline make?
peculiar odoro
aniline is insoluble in _________ but soluble in _________?
water, organic solvents
In the test for basicity what chemicals were used? Give its chemical formula?
Aniline (C6H5NH2), Water (H2O), Ferric chloride (FeCl3)
what was the product of basicity?
C6H5NH2+H2O —-> C6H5NH3 . OH (Anilinium hydroxide)
C6H5NH3.OH + Fe(Cl)3 —-> C6H5NH3.Cl + Fe(OH)3
what was the observable result of the test for basicity?
the presence of a brown precipitate formed indicating it to be oxidized. The Anilinium hydroxide turned the red litmus paper into a blue litmus paper. Inidicating it to be basic
how many ml of aniline was used in salt formation?
1/2 ml of aniline
the salt formation experiment created a product of?
C6H5NH2+HCl —–> C6H5NH3Cl Anilinium chloride
what was the observable results of the salt formation?
Presence of smoke was present
C6H5NH2+H2O —-> C6H5NH3.OH
C6H5NH3.OH + FeCl —-> Fe(OH)3 + C6H5NH3.Cl
What test was this?
Basicity
Presence of a brown precipitate? what test was this?
basicity
No changes were made however presence of smoke was present? What test was this?
Salt formation
by product of salt formation test?
C6H5NH3.Cl Anilinium chloride
what made the litmus paper in basicity test turn it to blue?
Anilinium hydroxide
