Sоdium phоsphаte, Nа3PO4(аq), is used tо clean oil stains from the surface of concrete. This cleaning solution contains 0.137 mol/L Na3PO4(aq), and the pOH of this solution was measured to be 1.36. The phosphate ion, PO43−(aq) would be classified as a(n) _i__ and the equation that would represent the single hydrolysis of this ion is ii .. Row i ii a. acid PO43−(aq) + H2O(l) HPO42−(aq) + OH−(aq) b. acid PO43−(aq) + H2O(l) H3PO4(aq) + OH−(aq) c. base PO43−(aq) + H2O(l) H3PO4(aq) + OH−(aq) d. base PO43−(aq) + H2O(l) HPO42−(aq) + OH−(aq)
