Solution Summary: The author explains the formula to calculate the pOH of the solution from the concentration of hydroxide ions.
The percentage of NH3, which is present in NH4+, is to be determined.
Concept introduction:
The ionization of a weak base takes place as
B(aq)+H2O(l)⇌OH−(aq)+HB+(aq)
The formula to calculate the pOH of the solution from the concentration of hydroxide ions is
pOH=−log[OH−] …… (1)
Kb is a measure of dissociation of a base and is known as base-ionization constant, which is specific at a particular temperature.
Kb=[OH−][BH+][B]
…… (2)
Percent ionization is the percentage of base that gets ionized upon addition of water. It depends on the hydroxide ion concentration or the conjugate acid concentration.
Here, [OH−]eq is hydroxide ion concentration at equilibrium, [BH+]eq is the conjugate acid concentration at equilibrium, and [B]o is original base concentration.
So I need help with understanding how to solve these types of problems. I'm very confused on how to do them and what it is exactly, bonds and so forth that I'm drawing. Can you please help me with this and thank you very much!
