Classify if H^2CO^3 is a strong or weak acid, or strong or weak base, or salt?
H2CO3 is commonly known as Carbonic acid. As the name suggests, this compound is an acid. Generally an acid, is a proton donor, has a pH below 7, neutralizes base and turns blue litmus paper to red. This also means that in a solution (in water) H2CO3 produces Hydronium ions (H3O+ ions).
The chemical equation for the dissociation of Carbonic acid (H2CO3) in the solution can be written as:
H2CO3 (aq) + H2O <---> H3O+ + CO3-
**hydronium ions can be represented as H3O+ or simply H+.
Carbonic acid is classified as a weak acid
