Additional information
A standard hydrolysis study with silane is considered technically unfeasible because the substance is a pyrophoric gas.
In a secondary source to which reliability could not be assigned, silane is attacked by water in the presence of minute traces of hydroxyl ion to evolve hydrogen and form silicic acid/silica or hydrated silicon dioxide. The reaction with water is further accelerated by larger amounts of inorganic or organic bases.
The final products on reaction with water and/or air are expected to be hydrogen, silicic acid (SiO2.nH2O) and/or silica.
In addition, in O'Neil 2013, silane was reported to slowly decomposes in water, and be practically insoluble in alcohol, ether, benzene, chloroform, silicochloroform and silicon tetrachloride, and to decompose in potassium hydroxide solutions.
