Question

What is the conjugate base of ch3ch2co2h?

Answer 1

The conjugate base of ch3ch2co2h or propanoic acid would be CH3CH2COO- or propanoate. The conjugate base is what is left after an acid has donated a proton in a reaction. Hope this answers the question. Have a nice day.

Answer 2

Answer : The conjugate base of propanoic acid, $CH_3CH_2COOH$ is, $CH_3CH_2COO^-$

Explanation :

According to the conjugate acid-base pair theory, an acid is a proton donor and a base is a proton acceptor.

The balanced conjugate acid-base pair reaction will be,

$CH_3CH_2COOH+H_2O\rightleftharpoons H_3O^++CH_3CH_2COO^-$

In this reaction, $CH_3CH_2COOH$ is a weak acid which donate a proton to $H_2O$ which is a weak base to form $CH_3CH_2COO^-$ as a conjugate base and $H_3O^+$ as a conjugate acid.

Hence, the conjugate base of propanoic acid, $CH_3CH_2COOH$ is, $CH_3CH_2COO^-$
