nitrates are copper (II) nitrate‚ lead (II) nitrate‚ zinc nitrate‚ magnesium nitrate‚ and silver nitrate. You can not manufacture the containers from glass due to possible breakage. Nor will plastic containers do because plastic tends to harden over time and also may shatter. This leaves metal. Unfortunately‚ many metals get eaten away (corrode)‚ when they come in contact with aqueous nitrates. Company documents indicate that copper‚ lead‚ zinc‚ and magnesium metals may work for aqueous nitrate

molybdenum and niobium are plentiful. The industry scale expands rapidly as the production volume of non-ferrous metals maintains rapid growth in recent years. The total production volume of the 10 major non-ferrous metals (copper‚ aluminum‚ lead‚ zinc‚ nickel‚ tin‚ stibium‚ magnesium‚ titanium and mercury) was 40‚287‚816 tons in China in 2013‚ up by 9.91% YOY. Major production regions of non-ferrous metals are Henan‚ Gansu‚ Hunan‚ Yunnan and Shandong. The production volume in the 5 regions accounted

Once only copper remains‚ we will then compare its’ absorbency to the other five post-1982 penny Cu concentrations made in this lab. INTRODUCTION: Before 1982 the US penny was made of pure copper. Because of the high cost of copper‚ the US government changed the composition of the penny. As of 1982‚ pennies have been made of mostly zinc‚ with a thin copper layer on the outside. The first step

Doing this showed me also that iron nitrate is an transition metal as well‚ same with the cobalt‚ copper‚ and zinc nitrate. (5 points) Score 3. Were there any metallic compounds that did not react with either the acid or the base? Write the type of metal‚ based on your examination of the periodic table.
