Lesson-specific diagram for Ionic dissociation equations and aqueous ions. It visualizes the reasoning sequence tied to $\mathrm{MX(s)\to M^{+}(aq)+X^{-}(aq)}$. Text alternative: Dissociation equations preserve atoms and charge and distinguish formula units from independently solvated ions. Choose a representation that matches the chemical scale and evidence; do not infer more precision or mechanism than the data support.
