The pH value of decinormal solution of NH4OH which is 20% ionised is
Concentration NH4OH solution = 0.1 N
Concentration of OH ions in solution,
Which of the following is strongest Bronsted base?
HClO4 is the strongest acid among HClO, HClO2, HClO3, and HClO4 as more the number of oxygen atoms attached, more is the acidity of the molecule order of acidity is :
HClO < HClO2 < HClO3 < HClO4
So the conjugate base order will be just reverse:
ClO- > ClO2- > ClO3- > ClO4-
