cobaltous

It is prepared by heating cobaltous sulfate with a solution of sodium bicarbonate.

Cobalt(II) oxide, also known as cobaltous oxide, is a chemical compound.

In classical times, cerulean was used to describe blue pigments, particularly mixtures of copper and cobaltous oxides.

Among these activators are magnesium, manganous zinc, ferrous, cobaltous, and nickelous ions, as well as others.

Dithiocarbamates readily react with many metal salts such as copper, ferrous, ferric, cobaltous, and nickel salts and are mostly found as octahedral complexes.

The pink form is cobaltous chloride hexahydrate, [CoCl2(H2O)4].2H2O.

Cobalt(II) hydroxide or cobaltous hydroxide is the chemical compound composed of cobalt and the hydroxide ion with the formula Co(OH).

Such double metal sulfates include ammonium cobaltous sulfate, ferric ammonium sulfate, ammonium nickel sulfate and ammonium ceric sulfate.

Cobalt(II) iodide or cobaltous iodide is the inorganic compound composed with the formula Co I. The two forms of CoI and the hydrated form are the principal iodides of cobalt.
