Final answer:
The concentration of K⁺ and SO₄²⁻ ions in a 0.200 M K₂SO₄ solution is also 0.200 M.
Step-by-step explanation:
To determine the concentration of the individual ions in a 0.200 M K₂SO₄ solution, we need to consider the dissociation of K₂SO₄ in water. K₂SO₄ dissociates into K⁺ and SO₄²⁻ ions.
Since the concentration of K₂SO₄ is 0.200 M, the concentration of K⁺ ions will also be 0.200 M. Similarly,
the concentration of SO₄²⁻ ions will also be 0.200 M.
