Stann′ate, a salt formed with stannic acid and a base.—adjs.

In the ensuing reaction the oxygen of the nitrate combines with the tin to form stannic acid, and this, in turn, combining with the alkali present, forms a stannate of that base, which, entering into solution, leaves the before-plated metal tin-free, the chloride present assisting in the reaction.

The tin contained in the stannate is deposited on the cotton in the form of stannic oxide, or, more strictly, stannic acid.

The hydroxides of tin and free stannic acid, which are easily liberated from these compounds, possess in very marked degree the power of fixing dyes upon fibers, as explained under aluminium.
