Consider this reaction: HCO3− + H2S → H2CO3 + HS−

Which is the conjugate acid?


H2S
HCO3-

HS–

H2CO3

Answer :

ARDNI313GO

The conjugate acid : H₂CO₃

Further explanation

Given

Reaction

HCO₃− + H₂S → H₂CO₃ + HS−

Required

The conjugate acid

Solution

Bronsted-Lowry

Acid ⇒ H⁺ + conjugate base

Bases + H⁺⇒ conjugate acids

Acid and conjugate base : H₂S and HS−

Base and conjugate acid : HCO₃− and H₂CO₃

H₂S gives (H⁺), then the remaining acid is a conjugate base  HS−

HCO₃− receives (H +), then the conjugate acid H₂CO₃

Answer:

The correct answer is D.
