2 HBr (aq) + Ca(OH)₂ (aq) → CaBr₂ (aq) + 2 H₂O (l)
Here's what's happening:
* Reactants:
* HBr (aq): Hydrobromic acid, a strong acid dissolved in water.
* Ca(OH)₂ (aq): Calcium hydroxide, a strong base dissolved in water.
* Products:
* CaBr₂ (aq): Calcium bromide, a soluble salt dissolved in water.
* 2 H₂O (l): Two molecules of water, a liquid.
Explanation:
This reaction is a classic acid-base neutralization reaction. The hydrogen ions (H⁺) from the acid react with the hydroxide ions (OH⁻) from the base to form water. The remaining ions (calcium and bromide) combine to form the salt, calcium bromide.
