Best Answer

Fe(II)(HSO3)2

Iron(II) bisulphite .

NB

  1. sulphurous acid is H2SO3 . Its anion is Sulphite (SO3^2-)

  2. The ''bi' means the sulphurous acid has only 'lost' ONE(1) hydrogen

Hence the sulphite becomes the 'bisulphite' (HSO3^-)

  1. Since the iron is in oxidation state '2' , its cation is Fe^2+. Hence it needs two 'bisulphite' anions to balance the charges.

NNB Do not confuse the 'bi' to mean 'two'. In this case it refers to the loss of hydrogen from the acid, in a similar way to sodium bi-carbonate (NaHCO3).

Hope that helps!!!!
