Telluric acid is a chemical compound. It is an acid. Its chemical formula is H6TeO6. It contains hydrogen and tellurate ions. It contains the TeO66- form of the tellurate ion.
Telluric acid is a weak acid. It reacts with strong bases to make tellurates. It is a powerful oxidizing agents. It can be dehydrated to make tellurium trioxide. The metatelluric acid, H2TeO4, does not exist.
Telluric acid can be made by reacting tellurium dioxide with chromium trioxide or hydrogen peroxide.
It is used to make other tellurates such as sodium tellurate.
