SUMMARY
The discussion centers on the equilibrium expression for the reaction NH3 + H2O ⇌ NH4+ + OH-. It clarifies that while H2O is typically included in the equation for Kb, it can be omitted in acid-base reactions involving NH4+. The dissociation constant for NH4+ is 5.6×10-10, confirming that NH4+ can act as a weak acid. The conversation also touches on the relationship between equilibrium constants and the substitution of OH- with Kw/H+.
