Why the vinegar can remove scale within the thermos
Mostly carbonate scale of components, in the majority with calcium carbonate, can react with acetic acid ions in vinegar to generate acetic acid salt soluble in water, water and carbon dioxide, and thus be decomposed to remove. Scale is a kettle and boiler as well as the poor condition of hot water of central heating system in the lining of the hard, gray or yellowish white chalk sediment
Because of the vinegar contains acetic acid composition, the components are mostly calcium carbonate scale, a few other material such as magnesium carbonate, acetic acid in vinegar ingredients can react with ditch of calcium carbonate, water and carbon dioxide is generated, thus achieved the effect of removal of incrustation.
Scale is mainly calcium carbonate, the vinegar was mostly acetic acid, reactive CaCO3 + 2 ch3cooh = Ca (CH3COO) 2 + CO2 + H2O, this reaction does not need to be harsh conditions, if add some hot water a little bit faster, product calcium acetate to go.
The main ingredient in scale of calcium carbonate and the main ingredients of acetic acid in vinegar that produce chemical reaction, the resulting soluble calcium acetate and carbon dioxide.
