3) -2 (SO4)

Answer 2

Valency of Sulfite, Bisulfite, and Sulfate

• The compound given in the questions are different types of ions formed by the element sulfur.
• To write the valency of these ions, knowledge about their chemical formula is essential.
• Accordingly, the formula of the given ions are as follows:

1. Sulfite - $SO_3^{2-}$
2. Bisulfite - $(HSO_3)^{-1}$
3. Sulfate - $SO_4^{2-}$

• The super scripted value on each formula denotes the number of electrons gained or donated which is considered as valency.
• The negative value indicates gained electron, whereas positive value indicates a donated electron.
• Thus accordingly the valency of the given substance is as follows:

1. Sulfite - 2 (As it gains 2 electrons)
2. Bi-sulfate - 1 (As it gains 1 electron)
3. Sulfate - 2 (As it gains 2 electrons)
