The pH value of decinormal solution of NH4OH which is 20% ionised is
12.95
12.30
14.70
13.30
B.
12.30
Concentration NH4OH solution = 0.1 N
Concentration of OH ions in solution,
Which of the following is strongest Bronsted base?
ClO-
ClO2-
ClO3-
ClO4-
A.
ClO-
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-
