Properties[change | edit source]
Thallium(I) carbonate is a white solid. It dissolves in water. It is the only heavy metal carbonate that can dissolve in water. It is similar to potassium carbonate. It is highly toxic, though. It reacts with acids like all carbonates do to make a thallium salt and carbon dioxide.
Preparation[change | edit source]
It is made by reacting thallium(I) oxide with carbon dioxide.
