Answer: The chemical formula for hydrogen sulfate and potassium permanganate is [tex]H_2SO_4[/tex] and [tex]KMnO_4[/tex] respectively.
Explanation:
The given two compounds are ionic compounds.
An ionic compound is defined as the compound which is formed by the complete transfer of electrons from one atom to another atom.
- For hydrogen sulfate:
Hydrogen is the 1st element of periodic table having electronic configuration of [tex]1s^1[/tex].
To form [tex]H^{+}[/tex] ion, this element will loose 1 electron.
Sulfate ion is a polyatomic ion having chemical formula of [tex]SO_4^{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.
So, the chemical formula for hydrogen sulfate is [tex]H_2SO_4[/tex]
- For potassium permanganate:
Potassium is the 19th element of periodic table having electronic configuration of [tex][Ar]4s^1[/tex].
To form [tex]K^{+}[/tex] ion, this element will loose 1 electron.
Permanganate ion is a polyatomic ion having chemical formula of [tex]MnO_4^{-}[/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.
So, the chemical formula for potassium permanganate is [tex]KMnO_4[/tex]
