WebbI believe this part of the problem should specify that all of the iron in the ore is converted to Fe 2+ (aq)). 1.7 mL of H 2 SO 4: This tells you the redox reaction between the KMnO 4 and the Fe 2+ is occuring in an acidic solution. The amount of H 2 SO 4 is not crucial here, since the limiting reagent in the titration will be the Fe 2+.
Iron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, just ahead of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust, being mainly deposited by meteorites in its metallic state, with its ores also being found there. citizens secure bank online loginWebb4 22 4 Si 4 35 4 W 4 W 4 49 4 54 403 a. m. 1000. p. lu. 123oC 2 01 S30" 4 OS. 210 240 4 14 529 541 545 5 50 5 55 » 10 (i IH 628 6 33 S3SI 1152 7 Ol 200 235 1 0» 1 39 2 13 2 45 2 53 2SS 3 09 3 22 324 3 2 4o SIM 657 800 11 00 Ml*.. it. m.. citizens secure bank onlineWebbYou will investigate the percentage by mass of iron in a sample of iron wire.
