Heated still more strongly, it becomes milk-white, oxygen is expelled, and it is converted into tellurous acid.
tellurous Acid (TeO2) is of a fine, granulous, crystalline or white earthy mass, which is partly soluble in water.
This solution is colorless, and is tellurous acid, dissolved in sulphuric acid.
Telluric acid produces the same reactions with the blowpipe reagents as tellurous acid.
With carbonate of soda, tellurous acid fuses upon platinum wire to a clear colorless bead, which is white when cold.
Telluric acid is reduced to tellurous (with evolution of chlorine) on boiling with hydrochloric acid.
