Use

Selenic acid, LIQUID reacts exothermically with chemical bases (for example: amines and inorganic hydroxides) to form salts. The reactions can generate dangerously large amounts of heat in small spaces. A good oxidizing agent. May oxidize organic matter such as wood, cotton, fiberboard, etc.. Reacts with active metals, including iron and aluminum, and also less active metals, to dissolve the metal and liberate hydrogen and/or toxic gases. Can initiate polymerization in certain classes of organic compounds. Reacts with cyanide salts and compounds to release gaseous hydrogen cyanide. Flammable and/or toxic gases are also often generated with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and weak or strong reducing agents. Additional gas-generating reactions occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and even carbonates: the carbon dioxide gas from the last is nontoxic but the heat and spattering from the reaction can be troublesome. May often catalyze (increase the rate) of chemical reactions.
