An unknown metal, x, was placed in a solution of CuCl2(aq) and black solid appeared on the metal. However, when metal x was placed in the solution of ZnCl2(aq), no observable change occurred. What is the possible identity of metal X? Explain your reasoning

1. A 0.9882 gram sample of iron ore is dissolved, the iron reduced to Fe2+, and the solution was titrated with 36.40 mL of 0.02065 M KMnO4 in acid solution. (a) Write the titration reaction. (b) Calculate the %FeO (M.M. = 71.85) in the sample.

12. A 0.3284-g sample of brass (containing lead, zinc, copper, and tin) was dissolved in nitric acid. The essentially insoluble SnO2•4H2O was removed by filtration, and the combined filtrate and washings were then diluted to 500.0 mL. A 10.00-mL aliquot was suitably buffered; titration of the lead, zinc, and copper in this aliquot required 37.56 mL of 0.002500 M EDTA. The copper in a 25.00 mL aliquot was masked with thiosulfate; the lead and zinc were then titrated with 27.67 mL of the EDTA solution. Cyanide ion was used to mask the copper and zine in a 100.0 mL aliquot; 10.80 mL of the EDTA solution was needed to titrate the lead ion. Determine the percent composition of the of the brass sample; evaluate the percent tin by difference.
