Introduction

In chemistry, writing the net ionic equation for a reaction is an essential step in understanding the underlying chemical processes. The net ionic equation is a simplified representation of the reaction, showing only the ions that participate in the reaction and their changes in state. In this article, we will focus on writing the net ionic equation for the reaction between silver nitrate (AgNO3) and sodium chloride (NaCl).

The Reaction

The reaction between silver nitrate and sodium chloride can be represented by the following equation:

AgNO_3(aq) + NaCl(aq) \rightarrow AgCl(s) + NaNO_3(aq)

This equation shows that silver nitrate reacts with sodium chloride to form silver chloride (AgCl) and sodium nitrate (NaNO3).

Step 1: Break Down the Reaction into Its Components

To write the net ionic equation, we need to break down the reaction into its components. We can start by identifying the ions present in the reactants and products.

Silver nitrate (AgNO3) contains the following ions:
- Silver (Ag+)
- Nitrate (NO3-)
Sodium chloride (NaCl) contains the following ions:
- Sodium (Na+)
- Chloride (Cl-)
Silver chloride (AgCl) contains the following ions:
- Silver (Ag+)
- Chloride (Cl-)
Sodium nitrate (NaNO3) contains the following ions:
- Sodium (Na+)
- Nitrate (NO3-)

Step 2: Identify the Ions that Participate in the Reaction

Next, we need to identify the ions that participate in the reaction. In this case, the silver (Ag+) and chloride (Cl-) ions are the ones that participate in the reaction.

Step 3: Write the Net Ionic Equation

Now that we have identified the ions that participate in the reaction, we can write the net ionic equation. The net ionic equation shows only the ions that participate in the reaction and their changes in state.

Ag^{+}(aq) + Cl^{-}(aq) \rightarrow AgCl(s)

This equation shows that the silver (Ag+) and chloride (Cl-) ions react to form silver chloride (AgCl).

Conclusion

In conclusion, writing the net ionic equation for the reaction between silver nitrate and sodium chloride involves breaking down the reaction into its components, identifying the ions that participate in the reaction, and writing the net ionic equation. The net ionic equation provides a simplified representation of the reaction, showing only the ions that participate in the reaction and their changes in state.
