WebJan 4, 2016 · Complexometric (EDTA) titrations Thermometric titrations employing sodium salts of ethylenediaminetetra-acetic acid (EDTA) have been demonstrated for the determination of a range of metal ions. Reaction enthalpies are modest, so titrations are normally carried out with titrant concentrations of 1 mol/L. WebProcedure-Part A: Titration of Hydrochloric acid with standard sodium hydroxide solution 1. Using a pipette and filler, transfer 50.0cm3 of NaOH solution into the polystyrene cup. Allow to stand for a few minutes. 2. Record the temperature of the solution 3. From a burette, add 5.0cm3 of HCl solution to the cup. 4.
WebSep 22, 2024 · Recall that at constant pressure (the conditions of this experiment), the heat released by the reaction equals the reaction enthalpy: qP = ΔH Since the heat released by each reaction is proportional to the amount of metal/metal oxide used, ΔH2 and ΔH3 can be easily calculated per gram or mole of metal/metal oxide used.
