Using equations only,show the formation of hydroxide ion in an aqueous solution of tetra
oxosulphate(vi) acid
H2SO4 + H2O → HSO4- + H3O+
HSO4- + H2O → SO42- + H3O+
2H2O → 2H+ + 2OH-
Combining these equations, we get:
H2SO4 + 2H2O → SO42- + 2H3O+ + 2OH-
Thus, the hydroxide ion is formed by the reaction of H2SO4 with water, leading to the generation of H3O+ and SO42- ions. The H3O+ ions further react with water molecules to form hydroxide ions (OH-).
