As more and more NaOH (aq) is added to the CH 3 COOH (aq) which is still in excess, the concentration of ions in solution, Na + (aq) and CH 3 COO-, becomes much greater than the concentration of H + (aq) due to the acid dissociation, so the electrical conductivity of the solution increases once again. NaCl) due to the very high conductivity of the hydrogen ion (H+). For Concentration, verify below table showing all elements and its respective ranges for selection. Calculating the limiting reactant, the change in enthalpy of the reaction, ∆H rxn, can be determined since the reaction was conducted under conditions of constant pressure ∆H rxn = q rxn / # moles of limiting reactant. In order to conduct electricity, a substance has to be able to allow an electrical charge to move through it. See Figure 1.
