Strength of Acid and Bases

[Sophia Diaz - Dis 1B]

When something is referred to as "less acidic" does that mean that it also a weaker acid and vise versa? How does the strength of acids refer to pKA because I don't really understand how it reflects acidic levels and strength?

[LilianKhosravi_1H]

when something is referred to as "less acidic" it's usually talking about the pH of something rather than the actual strength of the acid but a weak acid would cause little change in pH of a solution or make something acidic. An acid is strong when the pKA is lower and is weaker when the pKA is higher.

[John Miller-1I]

I agree that without more context besides "less acidic" I would assume that it is talking about a comparison between solutions with the less acidic one having a lower concentration of H30+

I would generally just refer to pH when it talks about being less acidic unless they specifically mention pKa's. Just easier to understand.
