Sodium telluride is a chemical compound. Its chemical formula is Na2Te. It contains sodium and telluride ions.
Properties[change | change source]
It is a white solid when pure. It reacts with air to make a mixture of tellurium and tellurides, which would make gray or purple colors. It eventually turns into sodium carbonate and tellurium when in air. It is a powerful reducing agent. It reacts with strong acids to make hydrogen telluride. It reacts with water to make sodium hydrogen telluride, NaHTe.
Preparation[change | change source]
Sodium telluride is made by reacting tellurium and sodium in liquid ammonia.
Uses[change | change source]
Sodium telluride is used to make organic tellurium compounds. It also can act as a reducing agent.
