- Reactants or equation
- AgNO3 + NaCl
Net ionic equation
- Reaction type
- Precipitation
- Spectator ions
- NO₃⁻, Na⁺
- Predicted products: AgCl + NaNO₃
- Balanced molecular equation: AgNO₃(aq) + NaCl(aq) → AgCl(s) + NaNO₃(aq)
- Complete ionic equation: Ag⁺(aq) + NO₃⁻(aq) + Na⁺(aq) + Cl⁻(aq) → AgCl(s) + Na⁺(aq) + NO₃⁻(aq)
- Cancelled spectators: NO₃⁻, Na⁺
- Net ionic equation: Ag⁺(aq) + Cl⁻(aq) → AgCl(s)
| Compound | State | Rule used |
|---|---|---|
| AgNO₃ | aq | Nitrates, acetates, chlorates, and perchlorates are soluble. |
| NaCl | aq | Group 1 and ammonium salts are soluble. |
| AgCl | s | Silver, lead, and mercury(I) halides precipitate. |
| NaNO₃ | aq | Group 1 and ammonium salts are soluble. |

The model predicts double-replacement products, balances atoms, and removes spectator ions. Weak acids and solid reactants remain molecular.
The result includes molecular, complete ionic, and net ionic equations with compound-state explanations.
- Predict AgCl precipitation when silver nitrate meets sodium chloride.
Predict silver chloride precipitation
Input: AgNO3 + NaCl
Settings: Reactants only; the tool predicts the products
Result: Ag⁺(aq) + Cl⁻(aq) → AgCl(s)
Na⁺ and NO₃⁻ remain in solution as spectator ions.

Supported compounds and reaction models
- The classroom model does not calculate concentration-dependent equilibrium.
- Redox, combustion, displacement, hydrates, and unlisted compounds need another method.
- The model fully dissociates sulfuric acid and dissolved calcium hydroxide.
- The model retains AgOH(s), although it can form silver oxide in practice.
