Question

Species acting as both Bronsted acid and base, is
(a) (HSO₄)⁻(b) Na₂CO₃ (c) NH₃ (d) OH⁻

Answer 1

answer : a. HSO4(-) and c.NH3 can act as bith bronsted acid and base

$- - - - - - - - - - - - - - - - - -$

solution and explaination :

bronsted acid : the compound or ion which can give out a proton (H+)

bronsted base : the compound or ion which accepts a proton (H+)

$- - - - - - - - - - - - - - - - - - - - - - -$

a. HSO4(-)

will accept a proton and become H2SO4

and also gives proton and becomes SO4(-2)

b. Na2CO3

will not accept and gives out any proton

c.NH3

will accept proton and becomes NH4+

and gives out proton and becomes NH2(-)

d.0H(-)

will accept proton and become H2O

but cannot donate any proton

therefore only a. and c. can act as both bronsted

acid and base

$- - - - - - - - - - - - - - - - - - - - - - - -$
