Answer: \(K^+\) and \(SO_4^-^2\)
Explanation: Potassium is a first group metal with one valence electron and so it has +1 charge. Sulfate ion is a polyatomic ion with -2 charge. The compound potassium sulfate has two potassium ions and one sulfate ion and the below equation shows how the ions are written when the compound is dissociated into its ions.
\(K_2SO_4\rightarrow 2K^++SO_4^-^2\)
