sulfuric acid

Although there’s evidence that it was once covered in oceans and could have been habitable, today it’s a scorched hellscape with clouds of sulfuric acid.

These include the water in low clouds and sulfuric acid spewed by volcanic eruptions.

Scientists have observed this new particle formation process with gases such as sulfuric acid, particularly over urban areas, where the chemical is abundant, and hypothesize that smog arises largely as a result of new particle formation.

Phosphine’s persistence in the clouds shrouding Venus suggests something must be currently producing it — otherwise the sulfuric acid in the planet’s upper atmosphere would have destroyed any signs of the gas by now.

For one thing, the Venusian clouds are exceedingly high in sulfuric acid, meaning the microbes would have had to evolve a way to deal with its corrosive effects.

Evaporate a portion of the extract to dryness and add sulfuric acid to the residue.

If sulfurous acid is present, it will be oxidized to sulfuric acid and precipitated as barium sulfate by the barium chlorid.

A white precipitate of barium sulfate will form if sulfuric acid is present.

Mix a bit of the powder with a small quantity of dry resorcin and add a few drops of concentrated sulfuric acid.

Heat at 200° C. till sulfuric acid fumes begin to come off and only a dry mass remains.
