Classify if H^2SO^4 is a strong or weak acid, or strong or weak base, or salt?
H2SO4 is commonly known as Sulfuric 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) H2SO4 produces Hydronium ions (H+ ions).
The chemical equation for the dissociation of Sulfuric acid (H2SO4 ) in the solution can be written as:
H2SO4 (aq) ---> H+ + HSO4- 1st protonation
HSO4- ----> H+ + SO4 2- 2nd protonation
**H2SO4 contains 2 H that can be protonated.
Sulfuric acid is classified as a strong acid.
