Is stannate tin?
The chemical symbol for tin is Sn. Practically, ‘stannate’ just means alkaline tin electroplating as opposed to acid tin plating (sometimes called stannous sulfate).

What is sodium stannate used for?
Description. Sodium stannate, formally sodium hexahydroxostannate(IV), is the inorganic compound with the formula Na2[Sn(OH)6]. This colourless salt forms upon dissolving metallic tin or tin(IV) oxide in sodium hydroxide, and is used as a stabiliser for hydrogen peroxide.
How do you make sodium Stannate?
In the present work, high-quality sodium stannate is prepared by reduction roasting of chemically pure tin dioxide and sodium carbonate under CO/CO2 atmosphere followed by diluted sodium hydroxide leaching.
What is potassium stannate used for?
Potassium Stannate is an alkaline tin plating electrolyte that produces a high quality deposit. It is also used for immersion tinning of aluminum alloys. It is non-corrosive to steel plating tanks and has higher current density and more concentrated solutions are possible because of its high solubility.

Will sodium hydroxide dissolve tin?
This colourless salt forms upon dissolving metallic tin or tin(IV) oxide in sodium hydroxide, and is used as a stabiliser for hydrogen peroxide.
Does sodium hydroxide react with tin?
Tin reacts with excess sodium hydroxide to form sodium stannite (Na2SnO2), sodium stannate(Na2SnO3) and hydrogen gas.
Is potassium chloride a metal?
Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine.
How zincate is formed?
Quick Reference. A salt formed in solution by dissolving zinc or zinc oxide in alkali. The formula is often written ZnO22− although in aqueous solution the ions present are probably complex ions in which the Zn2+ is coordinated to OH− ions.
What can dissolve tin?
Tin dissolves easily in concentrated acids, however, and in hot alkaline solutions, such as hot, concentrated potassium hydroxide (KOH).”
