solutions are stored in dark coloured plastic or wax coated glass vessels often with negative catalysts such as urea or sodium stannate added as stabilisers.
With stronger oxidizing agents is oxidized and in such cases is always evolved.
is more hydrogen bonded than is water and so has a higher boiling point than water.
In dilute aqueous solution is more acidic than water.
