You would not guess that they contain shiny metal. The earth's crust is made up of many minerals. Minerals can be defined as naturally occuring chemical elements and compounds. People have discovered more than 2,000 different minerals. Many of these contain metals. But because the metal elements are linked with other elements in the minerals, the metals do not show all of their properties. Figure A 1. Most minerals are elements, compounds 2. In order to free the metal from the other elements, a mineral must be synthesized, decomposed Page 3 I 6 Q +Suppose you wanted to analyze the amount of metal in the alloy. For example, you might want to determine the nickel (Ni2+) content in alloy material. (a) Using gravimetric analysis, propose precipitating method to analyze nickel (Ni2+) in alloy and write 8 steps required during the precipitation. Also, suggest an appropriate solvent and its ratio dissolve the mixture. Here we recommended using dimethylglyoxime (H2DMG) as an organic precipitating agent.(b) Suppose the nickel had been precipitated from the alloy (2.0980g) using dimethylglyoxime (H2DMG) as an organic precipitating agent and giving a precipitate of complex nickel dimethylglyoxime (Ni(HDGMG)2) weighing 0.2370g. Calculate the percentage weight of nickel (Ni2+) in the alloy sample.Question 27 of 40 Submit Construct the expression for Ksp for solid Ba3(P04)2 in aqueous solution.
