Iron and calcium metal ions are known to chelate with EDTA. Suppose the water used in preparation of your zinc chloride solution in the volumetric flask contained some levels of Pb2+ or Ca²+ metal. How will this affect the following? Explain your answers. (8 pts) 0.011 Consumed will increase ara result At of moles of EDTA increase I with Pb 2+ & Ca2+, Volume of EDTA solution a) The number of moles of EDTA calculated. The Nand of the moles of EDTA calculated will increase complexing As the EDTA Since Pb 2+ & Cat react with FOTA with 1/4 mou mamo, Hot roles of EDTA will increase Experiment 8 | Titration to Betermine the empirical Formats of zinc Chloride: Post-Lab 143
