Ba(NO₃)₂ (aq) + 2 NaOH (aq) → Ba(OH)₂ (s) + 2 NaNO₃ (aq)
Here's a breakdown of the reaction:
* Reactants:
* Barium nitrate (Ba(NO₃)₂) - a soluble ionic compound
* Sodium hydroxide (NaOH) - a soluble ionic compound
* Products:
* Barium hydroxide (Ba(OH)₂) - an insoluble solid (precipitate)
* Sodium nitrate (NaNO₃) - a soluble ionic compound
Explanation:
This is a double displacement reaction where the cations and anions of the reactants switch places. The insoluble barium hydroxide (Ba(OH)₂) precipitates out of solution, while the sodium nitrate (NaNO₃) remains dissolved.
Balancing the equation:
To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.
* Ba: 1 on each side
* N: 2 on each side
* O: 8 on each side
* Na: 2 on each side
* H: 2 on each side
The equation is now balanced.
