Limes have a [H3O+] of 1.3 x 10-2 mol/L. Their pOH is

To determine the pOH assuming water is the universal solvent take the value of 10 ^ -14 and then divide it by the hydronium concentration and then take the negative logarithm of the final answer that is the solution to the hydroxide ion concentration in the solution.

Well to my expert knowledge and my exquisite calculations i think the the negative ion # 412 is the key to sucess
