NaCN + H2O ---> CN-+ H3O++ Na+
In that equation Na+ is just a spectator ion,, further reaction with water results in:
CN- + H2O ---> HCN + OH- thus causing the resulting equation to be basic

The net ionic equation for the reaction between water (H2O) and sodium cyanide (NaCN) is:
H2O + CN- → HCN + OH-
To determine the net ionic equation, write out the balanced molecular equation first. Then, write the complete ionic equation with all ions separated. Finally, cancel out spectator ions (ions that appear on both sides of the equation) to arrive at the net ionic equation, which shows only the reacting ions.
To write a net ionic equation from a complete ionic equation, you remove the spectator ions that appear on both sides of the equation. The remaining ions that participate in the reaction are then included in the net ionic equation. This simplifies the equation to show only the ions that undergo a chemical change.
the spectator ions are removed
Yes, the complete ionic equation and the net ionic equation for a double replacement reaction can sometimes be the same. This occurs when all reactants and products are fully dissociated into ions in the reaction, leaving no spectator ions. In such cases, the complete ionic equation and the net ionic equation will be identical.
Yes, there are net ionic equation calculators available online that can help you determine the net ionic equation for a given chemical reaction. These calculators typically involve entering the balanced chemical equation for the reaction and then generating the net ionic equation based on the species that participate in the reaction.
