Characteristic
Telluric acid is a chemical compound with the formula Te(OH)6. It is a white solid made up of octahedral Te(OH)6 molecules which persist in aqueous solution. There are two forms, rhombohedral and monoclinic, and both contain octahedral Te(OH)6 molecules.Telluric acid is a weak acid which is dibasic, forming tellurate salts with strong bases and hydrogen tellurate salts with weaker bases or upon hydrolysis of tellurates in water.
Chemical formula:H6O6Te
Molar mass:229.64 g/mol
Appearance:White monoclinic crystals
Density:3.07 g/cm3
Melting point:136 °C (277 °F; 409 K)
Solubility in water:50.1 g/100 ml at 30 °C
Acidity (pKa):7.68, 11.0 at 18 °C Conjugate base Tellurate
Application
Telluric acid dihydrate is used in the preparation of tellurium nanorods through hydrazine-driven reduction, which finds application in solar cells, thermoelectric and topological insulators. It is also involved in the preparation of tellurium metal by reacting with the solution of potassium thiocyanate.
