Allied Chemical to manufacture one thousand containers. Allied Chemical needs the containers for storage of five kinds of aqueous nitrate solutions. The aqueous 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
