Laboratory of the Academy at
Florence
- heated
iodine
in
Olefiant gas
&
in
Carbonic oxide
.
a brown fluid formed in
olefiant
gas
; but in very small quantities only
& the greater part of the
iodine
remained unaltered this fluid was soluble
in water did not give it an acid
but rather a sort of etherial taste
-
iodine
exposed to
Carbonic oxide
in
vapour & in bright sun shine
appeared to act upon it a clear
fluid & a red fluid formed
the clear fluid had a strong stiptic
Taste but did not redden vegetable

sulphureous acid
gave a slight yellow
colour to Potassame fused
in it but |was| not neutralized by
it & the mixture dissolved in water

Hydroionic acid
Symbol/formula: HI
Now known as hydroiodic acid. This acid is formed from the combination of iodine with
hydrogen. Davy discusses making hydrionic acid in his 'Philosophical Transactions'
paper 'Some Experiments and Observations on a New Substance Which Becomes a Violet
Coloured Gas by Heat', published in 1814.

Carbonic oxide
Symbol/formula: CO
Now known as carbon monoxide, a colourless, odourless, poisonous and flammable gas.
