ACIDS & BASES

[Lesley Perez 1F]

How do you determine an acid base conjugate? Can someone give an example please I can't seem to get my head around it :(

Hello,

For acid and base conjugates, first you need to determine if the substance is an acid or a base. From there, you could write its conjugate acid/base. For example, say you have HCl. This is a well known strong acid, and so you would write its conjugate base. When water is the solution, and HCl is placed in it, then the conjugate base will be Cl-. You can think of it as simply losing the H atom, thus making it an anion. This is true for any conjugate base. The reverse is true of a conjugate acid, it would gain an H atom, thus making the conjugate acid a cation.

Hi, to determine an acid-base conjugate in a reaction you need to identify the molecules that differ by one proton (H+). The conjugate acid of a base is formed when the base gains a proton. The conjugate base of an acid is formed when the acid loses a proton. An example of this is the reaction "NH3 +H20 <-> NH4+ +OH-". In this reaction, NH3 is the base NH4+ is its conjugate acid, H20 is the acid and OH- is its conjugate base.

A conjugate acid contains one more H atom and one more + charge than the base that formed it. A conjugate base contains one less H atom and one more -charge than the acid that formed it.

To determine the conjugate acid-base pair, you need to consider the transfer of a proton (H⁺ ion) between the acid and base. The conjugate base is the species formed when an acid loses a proton.The conjugate acid is the species formed when a base gains a proton
