SUMMARY
In a 0.10 M H2SO4 solution, the predominant ions present in order of decreasing concentration are [H3O+] > [HSO4-] > [SO4-2] > [OH-]. The dissociation of sulfuric acid (H2SO4) in water leads to the formation of hydronium ions (H3O+) and hydrogen sulfate ions (HSO4-). Due to the strong acid nature of H2SO4, the first dissociation is complete, resulting in a significant concentration of H3O+ and HSO4-. The second dissociation to form sulfate ions (SO4-2) is less significant in this concentration.
