Here's a more accurate representation:
NH3 (aq) + H2O (l) ⇌ NH4+ (aq) + OH- (aq)
Explanation:
* NH3 (aq): Ammonia dissolved in water, forming an aqueous solution.
* H2O (l): Liquid water.
* NH4+ (aq): Ammonium ion, a positively charged ion formed when ammonia accepts a proton (H+) from water.
* OH- (aq): Hydroxide ion, a negatively charged ion formed when water loses a proton.
* ⇌: The double arrow indicates that the reaction is reversible. It can proceed in both directions, meaning that ammonium and hydroxide ions can react to form ammonia and water.
Key Points:
* Equilibrium: The reaction reaches a state of equilibrium where the rates of the forward and reverse reactions are equal.
* Basic Solution: The presence of hydroxide ions (OH-) makes the solution basic.
* Weak Base: Ammonia is a weak base because it only partially ionizes in water, meaning it doesn't donate all its electrons to form hydroxide ions.
This reaction is important because it demonstrates the basic nature of ammonia and its ability to accept protons in water. It's also relevant in understanding the pH of solutions containing ammonia.
