How Do You Compare Acid Strengths?

by | Last updated on January 24, 2024

, , , ,

The bond strength of an acid generally depends on the size of the ‘A’ atom: the smaller the ‘A’ atom,

the stronger the H-A bond

. When going down a row in the Periodic Table (see figure below), the atoms get larger so the strength of the bonds get weaker, which means the acids get stronger.

How do you show one acid is stronger than another?

How do you tell if an acid is strong or weak?

Any acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a

weak acid

.
