Production
Thorium(IV) hydroxide can be produced by reacting sodium hydroxide and soluble thorium salts.[1]
Reactions
New thorium(IV) hydroxide is soluble in acid but its solubility will decrease when older.[1]
Thorium(IV) hydroxide will break up at high temperature and produce thorium dioxide:
- Th(OH)4 → ThO2 + 2 H2O
At high pressure, thorium(IV) hydroxide reacts with carbon dioxide, and produce thorium carbonate hemihydrate.[2]
