Question

find the conjugate acid and base for H2O and HCO3 - ?

Answer 1

Conjugate acid and base of H2O are H30+ and OH-.
Conjugate acid and base of HCO3- are H2CO3 and (CO3)2-.

Answer 2

Answer:

The Correct Answer is mentioned below

Explanation:

Within the Brnsted–Lowry acid–base theory, a conjugate acid is a chemical molecule generated when an acid contributes a proton to a base—in other words, a base with a hydrogen ion added to it, whereas the reverse reaction loses a hydrogen ion.

The formula of the conjugate base is the formula of the acid less one hydrogen. The reacting base becomes the conjugate acid of the reactive base. The conjugate acid's formula is the base's formula plus one hydrogen ion.

Conjugate acid and base of $H_{2}O$ are $H_{3}O^{+}$ and $OH^{-}$.

Conjugate acid and base of $HCO_{3}^{-}$ are $H_{2}CO_{3}$ and $CO_{3}^{2-}$
