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-
When the temperature of reactions will increase then the effect on pH value will
increase
decrease
first increases then decreases
remains same.
The pH of aqueous solution ofammonium formate is (pKa of HCOOH = 3.8 and pKb of NH3= 4.8)
7
6.0
6.5
8.9
