Net Ionic Equation Calculator

The Net Ionic Equation Calculator converts a molecular equation into complete ionic and net ionic forms. It splits soluble ionic compounds into ions, identifies spectator ions that appear unchanged on both sides, and shows the species that actually participate in the reaction.

In aqueous solution, soluble salts dissociate into cations and anions. Strong acids and strong bases also dissociate fully. Spectator ions remain in solution without reacting. Removing them reveals the net ionic equation.

For example, mixing silver nitrate and sodium chloride gives:

$$\mathrm{AgNO_{3(aq)} + NaCl_{(aq)} \rightarrow AgCl_{(s)} + NaNO_{3(aq)}}$$

The complete ionic equation includes all dissolved ions. Sodium and nitrate are spectators. The net ionic equation is:

$$\mathrm{Ag^+_{(aq)} + Cl^-_{(aq)} \rightarrow AgCl_{(s)}}$$

Frequently Asked Questions

What is a net ionic equation?

A net ionic equation shows only the ions and molecules that undergo a chemical change. Spectator ions that appear unchanged on both sides are removed.

How do I identify spectator ions?

Write the complete ionic equation first. Any ion with the same formula, charge, and coefficient on both sides is a spectator and can be canceled.

What is the HCl and NaOH net ionic equation?

The net ionic equation for a strong acid-strong base reaction is H+(aq) + OH-(aq) → H2O(l). Sodium and chloride ions are spectators.

Do weak acids dissociate in net ionic equations?

Weak acids like HNO2 remain largely as molecules in solution. They are not split into ions in the complete ionic equation unless they react.
