Question

is there a conjugate acid of CH3COOH​

Answer 1

When acetic acid acts as a base (proton acceptor), its conjugate acid would be the acetonium ion. Its formula is (CH3COOH2)+.

Answer 2

Answer:

The conjugate acid of CH3COOH is ​CH₃-COOH₂.

Explanation:

Acid and base are related to each other. Every acid changes into a base after releasing a proton and every base on accepting a proton changes into an acid. Acids and bases thus exist as pairs and these pairs are called conjugate pairs. Thus, the conjugate acid differs from the conjugate base by one proton and vice versa.

CH₃-COOH + H₂O → H₃O⁺ + CH₃-COO⁻

Acetic acid releases a proton and changes into CH₃-COO⁻. Thus, CH₃-COOH is the acid and CH₃-COO⁻ is its conjugate base.

In HF, acetic acid act as a base and the conjugate acid formed is CH₃-COOH₂.

The reaction is given below.

HF + CH₃-COOH + →  F⁻ + CH₃-COOH₂
