WebSo, all of the H2SO4 will be neutralized and leave 0.0001 moles of NaOH. Now for the pH part. Remember that pH = 14 - pOH pOH = -log [OH-] The concentration of OH- will be equal to the number of moles of NaOH left divided by the total volume (10 + 7 mL or 0.017 L) or [OH] = 0.0001/0.017 = 0.00588 M so the pOH is WebSodium dihydrogen phosphate reacts with bases like sodium hydroxide resulting in the formation of sodium hydrogen phosphate and water. NaH2PO4 + NaOH → Na2HPO4 + H2O. Sodium dihydrogen phosphate …

WebApr 19, 2016 · How to calculate pH of a solution when $\ce{H3PO4}$, $\ce{NaH2PO4}$, $\ce{Na2HPO4}$ and $\ce{Na3PO4}$ are mixed together in certain amounts to form a solution? I know how to calculate pH when they are present individually but not when all of them together. I searched the net also but couldn't find any such example. It can be generated by neutralization of phosphoric acid with sodium hydroxide: H3PO4 + 2 NaOH → Na2HPO4 + 2 H2O Industrially It is prepared in a two-step process by treating dicalcium phosphate with sodium bisulfate, which precipitates calcium sulfate: CaHPO4 + NaHSO4 → NaH2PO4 + CaSO4 In the … See more Disodium phosphate (DSP), or disodium hydrogen phosphate, or sodium phosphate dibasic, is the inorganic compound with the formula Na2HPO4.
