Question

Draw the conjugate acid for the following base. Remember to include charges and non-bonding electrons where necessary.

Answer 1

Answer:

A conjugate acid will change to conjugate base by accepting one proton.

According to Brønsted–Lowry acid–base theory, an acid is a specie which has tendency to lose an electron while a base is an specie which has tendency to accept an electron.

Hence a conjugate pair is a pair of acid and base which are differ in only one proton.

Explanation with example:

HCl is acid which is a part of conjugate pair.

If HCl lose a proton it changes to Cl- which is conjugate base of an HCl acid. And this conjugate base will change to conjugate acid by accepting one proton.

Hence the reaction is:

                                                        Cl- + H+ → HCl
