It is very unstable, decomposing slowly even at ordinary temperatures.
It is not very stable, water decomposing it into alcohol and the alkaline carbonate.
Of metals not decomposing liquid pure water, only a few dissolve in aqueous caustic potash or soda, with evolution of hydrogen.
The solution, if boiled, deposits its titanic oxide as a hydrate called metatitanic acid, TiO(OH) 21 because it differs in its properties from orthotitanic acid, Ti(OH) 4, obtained by decomposing a solution of the chloride in cold water with alkalis.
It resembles calcium carbide, decomposing rapidly with water, giving acetylene.
