Tin(II) oxide burns in air with a dim green flame to form SnO 2. [4] 2 SnO + O 2 → 2 SnO 2. When heated in an inert atmosphere initially disproportionation occurs giving Sn metal and Sn 3 O 4 which further reacts to give SnO 2 and Sn metal. [4] 4SnO → Sn 3 O 4 + Sn Sn 3 O 4 → 2SnO 2 + Sn
SnO 2 + 2 H 2 SO 4 → Sn(SO 4) 2 + 2 H 2 O. The latter compound can add additional hydrogen sulfate ligands to give hexahydrogensulfatostannic acid. [16] SnO 2 dissolves in strong bases to give "stannates," with the nominal formula Na 2 SnO 3. [11] Dissolving the solidified SnO 2 /NaOH melt in water gives Na 2 [Sn(OH) 6], "preparing salt ...
The anhydrous form of sodium stannate, Na 2 SnO 3, is recognised as a distinct compound with its own CAS Registry Number, [4] 12058-66-1, and a distinct material safety data sheet. [5] Alkali metal stannate compounds are prepared by dissolving elemental tin in a suitable metal hydroxide, in the case of sodium stannate by the reaction: [6]
Tin(II) sulfate (Sn S O 4) is a chemical compound. It is a white solid that can absorb enough moisture from the air to become fully dissolved, forming an aqueous solution; this property is known as deliquescence. It can be prepared by a displacement reaction between metallic tin and copper(II) sulfate: [3] Sn (s) + CuSO 4 (aq) → Cu (s) + SnSO ...
Tin(II) hydroxide, Sn(OH) 2, also known as stannous hydroxide, is an inorganic compound tin(II). The only related material for which definitive information is available is the oxy hydroxide Sn 6 O 4 (OH) 4, but other related materials are claimed. They are all white solids that are insoluble in water.
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

In chemistry, the term stannate or tinnate refers to compounds of tin (Sn). Stannic acid (Sn(OH) 4 ), the formal precursor to stannates, does not exist and is actually a hydrate of SnO 2 . [ 1 ] The term is also used in naming conventions as a suffix; for example the hexachlorostannate ion is SnCl 2−
A molecule is said to have a positive oxygen balance if it contains more oxygen than is needed and a negative oxygen balance if it contains less oxygen than is needed. [2] An explosive with a negative oxygen balance will lead to incomplete combustion, which commonly produces carbon monoxide, which is a toxic gas. Explosives with negative or ...
