- "What is the formula for the product formed whenFe2+and 1,10-phenanthrolinereact?" (the anwsers i need are parts a-c at the bottom of the post) I used a spectrometer to find where adding iron to a phen solution stops it from increasing its absorption. It stops after the volume of iron hits 2.225 mL in a 50.00 mL phen solution. (ill show it in an attached image) Fe2+ has a concentration of 2.500 x 10^-3 phen solution has a concentration of 2.70x10-4 I need you to do the following equations step by step in a way that i can understand: a) Calculate the moles Fe2+in the Fe2+volume at the stoichiometric point at aliquot 9 b) Calculate the ratio of phen/Fe2+using the total moles of phen from the original phen solution and total moles of Fe2+from part a) at the stoichiometric point. c) Using the ratio from part b, write the complete balanced reaction for Fe2+with 1,10-phenanthrolineto produce the ferroin product.Heptanet-4-hione LA predicted solubility (with a reason) in the following representative solvents/solvent systems H20, Dilute HCI, Dilute NazCO3, Dilute NaOH, ELOH; acetone; CHCIB; Hexane.Chemistry Estimation of Rhodamine B in Wastewater-UV-VIS Spectrophotometry
