Stannic

There is also an acid, H_ SnO_ , called stannic acid, which forms a series of salts called stannates. ❋ William McPherson (N/A)

I may also, in the last instance, mention that I have found the above methods of electro-dissolution peculiarly adapted for the preparation of unstable compounds such as stannic nitrate, potassic ferrate, ferric acetate, which are decomposed on the application of heat, and in some instances have succeeded by the following means of crystallizing the resulting compound obtained. ❋ Various (N/A)

The ease with which stannous chloride takes up chlorine to form stannic chloride makes it a good reducing agent in many reactions, changing the higher chlorides of metals to lower ones. ❋ William McPherson (N/A)

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. ❋ William McPherson (N/A)

By treating a solution of stannous chloride with aqua regia, stannic chloride is formed: ❋ William McPherson (N/A)

~ In nearly all its compounds lead has a valence of 2, but a few corresponding to stannic compounds have a valence of 4. ❋ William McPherson (N/A)

By heating chromate of stannic oxide to bright redness, a dark violet mass is obtained, which is better adapted to enamel painting than to the palette. ❋ George Field (N/A)

After standing about twelve hours in a covered beaker the precipitate was filtered off and the tin weighed as stannic oxide. ❋ Various (N/A)

What are the products of hydrolysis when stannic chloride is used as ❋ William McPherson (N/A)

Although not to be ranked with ultramarine, the stannic and aluminous blues may be described as durable, or at least as durable rather than semi-stable. ❋ George Field (N/A)

Tin is usually said to be dyad in stannous compounds and a tetrad in stannic compounds, but in a compound like SnCl_ {2} AmCl, is not tin really a tetrad? ❋ Various (N/A)

The tin contained in the stannate is deposited on the cotton in the form of stannic oxide, or, more strictly, stannic acid. ❋ Franklin Beech (N/A)

They are divisible into three classes -- the stannic cerulian blue, the aluminous cobalt blues, and the siliceous smalts. ❋ George Field (N/A)

By igniting strongly for some hours a mixture of stannic oxide, chalk, chromate of potash, and a little silica and alumina, a dingy red mass is obtained, which acquires a beautiful rose-red colour on being washed with water containing hydrochloric acid. ❋ George Field (N/A)

SnCl_ ; the stannic, in which it is tetravalent as shown in the compounds SnO_ , SnS_ . ❋ William McPherson (N/A)

The tin sulphide only dissolves; it is filtered off and converted into stannic acid, while the lead sulphide is transformed into sulphate and weighed as such. ❋ Various (N/A)

It is attacked by nitric acid, yielding a white powder of stannic phosphate; this is not easily decomposed by ammonium sulphide or readily soluble in hydrochloric acid. ❋ Cornelius Beringer (1886)

The reduced metal is only slowly dissolved by hydrochloric acid, and although it is readily soluble in aqua regia, the solution cannot be evaporated or freed from the excess of acids, by boiling, without loss of tin, because of the volatility of stannic chloride. ❋ Cornelius Beringer (1886)

Boil till the bulk is reduced by one-half, dilute with 50 c.c. of water, allow to settle for a few minutes, and filter; wash well first with water acidulated with a little nitric acid, and afterwards with water; dry, ignite, and weigh as stannic oxide. ❋ Cornelius Beringer (1886)

Wash the precipitate with hot water, dry, calcine gently; ignite with ammonium carbonate, and weigh as stannic oxide, SnO_ {2}. ❋ Cornelius Beringer (1886)
