Question

Two hypothetical acids HA and HB have the dissociation constants 2 × 10⁻⁶ and 2 × 10⁻⁸ respectively in water at 25°C. Calculate the strength of HA with respect to HB.

Answer 1

Answer:

Answer

The dissociation constants of HA

1

and HA

2

are 3×10

−4

and 1.8×10

−5

.

The strength of an acid is directly proportional to square root of dissociation constants of acids. So relative strength of the given acids are:

(Acidic Strength)

HA

2

(Acidic Strength)

HA

1

=

(Dissociation Constant)

HA

2

(Dissociation Constant)

HA

1

Relative Acidic Strength=

(AcidicStrength)

HA

2

(AcidicStrength)

HA

1

=

1.8×10

−5

3.0×10

−4

=4.08=4(approx)

relative strengths of acids will be 4:1.
