Question

Identify the conjugate acid-base pairs. H2CO3 and H2O H3O and H2O HCO3 - and H3O H2CO3 and H3O HCO3 - and H2O HCO3 - and H2CO3

Answer 1

Step-by-step explanation:

H₃O⁺ and H₂O .

H₂O + H⁺ ⇄ H₃O⁺

H₂O accepts proton to form H₃O⁺ so H₂O is base .

H₃O⁺ ⇄ H₂O + H⁺

Here H₃O⁺ is acid because it gives proton ( H⁺ ) .

HCO₃ ⁻ and H₂CO₃

H₂CO₃ ⇄ HCO₃ ⁻ + H⁺

H₂CO₃ is acid because it gives proton ( H⁺ )

HCO₃ ⁻ + H⁺ = H₂CO₃

HCO₃ ⁻ is base because it accepts proton .
