Detailed Solution: Question 1
also increases.The number of species of the following that can act both as Bronsted acids and bases is 
, 
, Detailed Solution: Question 2
(Bronsted acid)
(Bronsted base)
(Bronsted base)
(Bronsted acid)
(Bronsted base)
(Bronsted acid)
(Bronsted base)
and 
(two species act as acid as well as base).
of 
is added to 
of 
barium hydroxide solution. What is the 
of the resulting solution?
of is added to of barium hydroxide solution. What is the of the resulting solution?Detailed Solution: Question 3
Which equilibrium can be described as an acidbase reaction using the Lewis acid-base definition but not using the Bronsted-Lowry definition?
Detailed Solution: Question 4
involves loss and gain of electrons.
is coordinated to 
by donating electrons (LHS). It is then removed by withdrawing electrons.What is the decreasing order of basic strengths of 
and 
and Detailed Solution: Question 5
conjugate base will follow the order
Values of dissociation constant, are given as follows:
Correct order of increasing base strength of the base and will be:
Correct order of increasing base strength of the base and will be:
Detailed Solution: Question 6
lower will be the value of 
i.e. higher will be the acidic nature. Further 
and 
are conjugate base of the acids 
and 
respectively hence the correct order of base strength will be
Given
(i) 
(ii) 
These equilibria show the following order of the relative base strength,
(i)
(ii)
These equilibria show the following order of the relative base strength,
Detailed Solution: Question 7
The degree of dissociation of 
weak acid HA is 
. If 
of 
solution is diluted to 
the degree of dissociation of acid and 
ion concentration in the resulting solution will be respectively
weak acid HA is . If of solution is diluted to the degree of dissociation of acid and ion concentration in the resulting solution will be respectivelyDetailed Solution: Question 8
Acidity of 
can be explained on the basis of which of the following concepts?
Detailed Solution: Question 9
is 
is electron deficient i.e, lone-pair of electrons acceptor (Lewis acid), because in 
, 
is 
hybridised and it does not satisfy octet ( 
has say bonded electrons).
The hydrogen ion concentration of 
which is 
dissociated is
which is dissociated isDetailed Solution: Question 10
