NH3 + H^(from HNO3) ==> NH4^+
The equation you want is the above one.
How it works is below.
pH = pKa + log (NH4^+)/(NH3)
So when HNO3 is added to the solution, the NH3 reacts with it to form NH4^+, it increases NH4^+ and decreases NH3
I need to know how to write an equation showing how a buffer containing ammonia and ammonium chloride neutralizes added acid of HNO3.
