(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 storage. But

Chemical decomposition can be defined as the separation of chemical compounds into smaller‚ simpler compounds (New World Encyclopedia‚ 2009). It is often considered an undesirable outcome of a chemical reaction. Radiation‚ humidity‚ heat‚ and acidity affect the stability of chemical compounds. Molecules‚ when put under harsh environmental conditions may break up into smaller particles. Decomposition can also be defined as the breakdown of one phase into two or more phases. Thermal‚ electrolytic‚
