Alex17521 [72]

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>

<em></em>

I hope it helps!
