Ca(NO₃)₂ (aq) + 2 NaOH (aq) → Ca(OH)₂ (s) + 2 NaNO₃ (aq)
Here's a breakdown of the reaction:
* Reactants:
* Calcium nitrate (Ca(NO₃)₂) is a soluble ionic compound.
* Sodium hydroxide (NaOH) is also a soluble ionic compound.
* Products:
* Calcium hydroxide (Ca(OH)₂) is an insoluble ionic compound, which precipitates out of solution as a solid.
* Sodium nitrate (NaNO₃) is a soluble ionic compound that remains in solution.
Explanation of Balancing:
* Calcium (Ca): We have one Ca atom on each side of the equation.
* Nitrogen (N): We have two N atoms on each side.
* Oxygen (O): We have six O atoms on each side.
* Sodium (Na): We have two Na atoms on each side.
* Hydrogen (H): We have two H atoms on each side.
The equation is balanced because the number of each type of atom is the same on both the reactant and product sides.
