Is a carbonic acid weak or strong?

Answer 1

H2CO3 is a weak acid--you can tell because there is one less H than O. Strong ternary acids have at least 2 less H than O (for instance, H2SO4, HClO3, HClO4). Strong binary acids are made of halogens, except for weak HF (so they are HCl, HBr, HI).

Answer 2

Carbonic acid is considered a weak acid, as it only partially ionizes in water to produce hydrogen ions and bicarbonate ions. This results in a relatively low concentration of free hydrogen ions in solution compared to a strong acid like hydrochloric acid.

Answer 3

weak

Answer 4
