2KOH(aq) + BaCl₂(aq) → 2KCl(aq) + Ba(OH)₂(s)
Here's a breakdown of the reaction:
* Reactants:
* Potassium hydroxide (KOH) is a strong base, typically dissolved in water as an aqueous solution.
* Barium chloride (BaCl₂) is a soluble salt, also typically dissolved in water as an aqueous solution.
* Products:
* Potassium chloride (KCl) is a soluble salt that remains dissolved in the solution.
* Barium hydroxide (Ba(OH)₂) is a slightly soluble strong base that precipitates out of the solution as a white solid.
Important Notes:
* This reaction is driven by the formation of the insoluble barium hydroxide precipitate. This removes Ba(OH)₂ from the solution, favoring the forward reaction.
* The reaction is typically carried out in aqueous solutions.
* The solubility of barium hydroxide is relatively low, meaning that a white solid will form as the reaction proceeds.
* This reaction is a classic example of a double displacement reaction, where the cations and anions of the reactants switch partners.
Safety Considerations:
* Barium hydroxide is toxic and should be handled with care.
* Always wear appropriate safety gear when working with chemicals.
