Silver nitrate (AgNO₃) is a strong electrolyte, meaning it dissociates completely into its ions when dissolved in water.
### The reaction that occurs when solid silver nitrate is put into water:
When AgNO₃ is added to water, it dissociates into silver ions (Ag⁺) and nitrate ions (NO₃⁻).
The dissociation reaction can be written as:
\[
\text{AgNO}_3 (s) \rightarrow \text{Ag}^+ (aq) + \text{NO}_3^- (aq)
\]
### Explanation:
- **AgNO₃ (s)** represents solid silver nitrate.
- When dissolved in water, strong electrolytes like silver nitrate dissociate into their constituent ions.
- **Ag⁺ (aq)** indicates silver ions in aqueous solution.
- **NO₃⁻ (aq)** indicates nitrate ions in aqueous solution.
Since silver nitrate is a strong electrolyte, this dissociation is complete, meaning all AgNO₃ molecules separate into their ions. This results in the formation of free-moving ions in water, which is why solutions of strong electrolytes conduct electricity well.
