Question

What is the formula for magnesium sulfite ?

Answer 1

MgSO3

Step-by-step explanation:

Answer 2

Answer: The chemical formula for magnesium sulfite is
`MgSO_3`

Step-by-step explanation:

The given compound is formed by the combination of magnesium and sulfite ions. This is an ionic compound.

Magnesium is the 12th element of periodic table having electronic configuration of
`[Ne]3s^2`.

To form
`Mg^(2+)` ion, this element will loose 2 electrons.

Sulfite ion is a polyatomic ion having chemical formula of
`SO_3^(2-)`

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

So, the chemical formula for magnesium sulfite is
`MgSO_3`
