Bonjour,
1) Lorsque la solution est conductrice, cela implique qu'elle contient des ions sans lesquels les électrons ne pourraient pas se déplacer. Les solides non ioniques ne se dissolvent donc pas .
2) Equations de dissolution des solides solubles :
CuCl₂(s) → Cu²⁺(sol) + 2Cl⁻(sol)
MgCl₂(s) → Mg²⁺(sol) + 2Cl⁻(sol)
Al₂(SO₄)₃(s) → 2Al³⁺(sol) + 3SO₄²⁻(sol)
