03.11.2012· For example, Na2SO4 is reduced to Na2S easily in a furnace when roasted with charcoal. It is far more energetically favourable for aluminium metal to reduce the sulfate to sulfide, instead of actually "stealing" off the sulfate anion. Any potential calcium metal formed will also react with the sulfate quickly to form oxides of calcium and sulfides.

Aluminium ion Reactions [MarZ Chemistry]

One type of reaction is not enough, to confirm the presence of aluminium, since other metal salts give the same results. For Example with NaOH, many metals give a white ppt., and hence one can''t say that the formation of a white ppt of an unknown sample with NaOH is 100% due to Aluminium ions.

It''s Elemental - The Element Calcium

Although calcium is the fifth most abundant element in the earth''s crust, it is never found free in nature since it easily forms compounds by reacting with oxygen and water. Metallic calcium was first isolated by Sir Humphry Davy in 1808 through the electrolysis of a mixture of lime (CaO) and mercuric oxide (HgO).
