Problem: Calculate [H3O+], [ClO4-], and [OH-] in an aqueous solution that is 0.125 M in HClO4(aq) at 25 °C.Is the solution acidic, basic or neutral?

FREE Expert Solution

HClO4

possess H+ ions (HClO4) connected to nonmetal and oxygen (Cl and O) → oxyacid
there are 3 more O than H → strong acid


HClO4 → strong acid → completely ionize in the solution:

HClO4(aq) + H2O(l) → H3O+(aq) + ClO4-(aq)


Given:            [HClO4] = 0.125 M
