Give your answer to two decimal places and in scientific notationI just need help in the Calculations EXPERIMENT: ESTIMATION OF SODIUMHYDROXIDE USING HYDROCHLORIC ACID (CONDUCTOMETRIC TIITRATION) Aim: To determine the mass of NaOH in the given solution by conductance measurement. Apparatus & Chemicals: 0.1N, 100 ml HCl , weighing balance, burette, pipette, beaker, funnel, standard flask, glass rod, distill water Theoretical Background: When sodium hydroxide is added to HCl, the highly mobile H+ ions are replaced by less mobile metallic ions. Before the alkali is added, the acid solution has a high conductance due to the highly mobile H+ ions. Observations: Volume of NaOH added (ml) Conductance Volume of NaOH added (ml) Conductance 1 5.5 13 1.3 2 5.3 14 1.0 3 5.1 15 0.7 4 4.6 16 0.4 5 4.2 17 0.1 6 3.8 18 0.5 7 3.3 19 0.9 8 2.9 20 1.2 9 2.6 21 1.7 10 2.2 22 2.2 11 1.9 23 2.5 12 1.6 24 2.9 Calculations:…Calculate the concentration (M) of the anion Z2- for a 0.100 M solution of H2Z given the acid ionization constants for the acids below.
