Answer: Option (B) is the correct answer.
Explanation:
The given compound is [tex]K_{2}SO_{4}[/tex], that is, it contains potassium [tex](K^{+})[/tex] and sulphate [tex](SO^{2-}_{4})[/tex] ions.
Charge on a sulphate ion is -2 and charge on two potassium ions is +2. Therefore, according to cross multiplication method it results in the formation of [tex]K_{2}SO_{4}[/tex].
Thus, we can conclude that chemical name of the compound is potassium sulfate.
