30. In the following equation which one of the compounds is acting as an acid H2(SO4) + H2O --> HSO4- + H3O+
a. H2O (Incorrect)
b. H2SO4
c. H3O+
d. HSO4-
e. none of the above

Solution

H2SO4 + H2O --------------------> HSO4^- + H3O⁺

species which can donate proton is considered as acid.

in above reaction H2SO4 giving proton to H2O

so H2SO4 acting as acid

answer = option b = H2SO4
