Properties

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

Sodium telluride is made by reacting tellurium and sodium in liquid ammonia.

Uses

Sodium telluride is used to make organic tellurium compounds. It also can act as a reducing agent.
