Answer: The chemical formula for potassium sulfite is [tex]K_2SO_3[/tex]
Explanation:
We are given a chemical compound having name potassium sulfite. This compound is formed by the combination of potassium ions and sulfite ions.
Potassium is the 19th element of periodic table having electronic configuration of [tex][Ar]4s^1[/tex].
This element will loose 1 electron to form [tex]K^{+}[/tex] ion
Sulfite ion is a polyatomic ion having chemical formula of [tex]SO_3^{2-}[/tex]
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.
Hence, the chemical formula for potassium sulfite is [tex]K_2SO_3[/tex]
