After all of that, the mixture is strained and formed into fibers through yet another round of chemicals—this time sulfuric acid.

In February, an upset at the refinery showered oil on people’s homes, gardens and drinking-water supplies more than two miles away, and last month sulfuric gases escaped from the plant.

Ash prevents incoming sunlight from heating the ground, while sulfuric aerosols lofted into the stratosphere can interact with water molecules and reflect sunlight back out to space.

Visitors can explore hot turquoise pools, hissing sulfuric vents, and boiling mudpots from the safety of the trail.

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.
