It is the sodium salt of arsenous acid.

And then you cook them up with nitre and you get arsenous acid, sir.

Arsenous acid is a colorless solution.

'The wick's full of arsenous acid,' she said.

It reacts with water to make arsenous acid and hydrofluoric acid, both very dangerous acids.

Hydrolysis with water gives arsenous acid and hydrochloric acid:

'It could be arsenous acid, sir.

Lewisite, like other arsenous chlorides, hydrolyses in water to form hydrochloric acid:

The reaction proceeds via formation of arsenous acid which exists in equilibrium with hydroiodic acid.

Unlike phosphorus acid, arsenous acid is genuinely tribasic, with the formula As(OH).

There are scores of minerals found only here, such as Johnbaumite (an arsenous apatite), McGovernite, etc.

Firstly, it acts as a de-oxidiser, reacting with oxygen in the hot metal to form arsenous oxides which vaporise from the liquid metal.

The H NMR spectrum of arsenous acid solutions consists of a single signal consistent with the molecule's high symmetry.

In 1833 Bunsen became a lecturer at Göttingen and began experimental studies of the (in)solubility of metal salts of arsenous acid.

It melts at -16 C and boils at 130.2 C. It reacts with water, similar to phosphorus trichloride, to make arsenous acid and hydrochloric acid.
