Answer:
K₂S(s) → 2K⁺(aq) + S²⁻(aq)
Explanation:
A strong electrolyte is a compound that, in solution, dissociates completely. For a compound XₐYₙ that dissolves in water:
XₐYₙ(s) → aXⁿ⁺(aq) + nYᵃ⁻(aq)
Now, potassium sulfide (K₂S), as a strong electrolyte dissolves in water thus:
<em>K₂S(s) → 2K⁺(aq) + S²⁻(aq)</em>
