It is mainly useful for the determination of a mixture of different metal ions in solution.
WebOne such titration involves the use of sodium carbonate (Na2CO3) and hydrochloric acid (HCl). In this titration, a solution of known concentration of HCl is added to a solution of unknown concentration of Na2CO3 until the reaction between the two is complete. The point at which the reaction is complete is known as the endpoint, and is typically ... WebOn the mixture titration curve find the pH at each end point. For purposes of illustration assume one is at pH 5 and the other at pH 10. On the sulfamic acid titration curve find the volumes of NaOH required to titrate to pH = 5 and to pH = 10. Use the first volume and the mmol of sulfamic acid used
