Write a balanced equation for the dissociation of each of the following strong electrolytes in water:d. Fe(NO₃)₃

Verified step by step guidance

1. Identify the strong electrolyte: Fe(NO_3)_3 is iron(III) nitrate, a strong electrolyte that dissociates completely in water.
2. Determine the ions produced: When Fe(NO_3)_3 dissociates, it forms Fe^{3+} ions and NO_3^- ions.
3. Write the dissociation equation: Start with the solid form of the compound on the left side of the equation.
4. Balance the equation: Ensure that the number of atoms and the charge are balanced on both sides of the equation.
5. The balanced equation will show Fe(NO_3)_3 dissociating into one Fe^{3+} ion and three NO_3^- ions.

Key Concepts

Strong Electrolytes

Strong electrolytes are substances that completely dissociate into ions when dissolved in water. This means that they exist entirely as ions in solution, which allows them to conduct electricity effectively. Common examples include soluble salts, strong acids, and strong bases. Understanding strong electrolytes is crucial for predicting the behavior of ionic compounds in aqueous solutions.

Dissociation Reaction

A dissociation reaction refers to the process by which an ionic compound separates into its constituent ions in a solvent, typically water. For example, when iron(III) nitrate, Fe(NO₃)₃, is dissolved in water, it breaks down into iron ions (Fe³⁺) and nitrate ions (NO₃⁻). Writing a balanced equation for this process involves showing the reactants and products, ensuring that the number of atoms and charges are conserved.

Balancing Chemical Equations

Balancing chemical equations is the process of ensuring that the number of atoms of each element is the same on both sides of the equation. This is essential for adhering to the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. In the case of dissociation reactions, it is important to balance both the number of ions produced and their respective charges to accurately represent the reaction.
