When the temperature of reactions will increase then the effect on pH value will
increase
decrease
first increases then decreases
remains same.
Smallest intermolecular distance is found in
O2
O2+
O2-
O22-
B.
O2+
In O2, the bond order = 2
In O2+, the bond order = 2.5
In O2-, the bond order = 1.5
In O22-, the bond order = 1
As the bond order in O2+ is highest, so its internuclear distance is smallest
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
