Hydrogen Peroxide, 30 Percent, Solution, Reagent is the simplest peroxide, a strong oxidizer that appears as a clear and slightly viscous liquid. Its oxidizing properties are so strong that it is considered a highly reactive oxygen species. Due to it being a weak acid, it can form thermally unstable hydroperoxides. One of its biggest uses is in the treatment of drinking water, removing odors, organic materials and the amount of Hydrogen sulfides and Iron. As a Reagent grade, Spectrum Chemical manufactured Hydrogen Peroxide is a high quality chemical suitable for use in many analytical and general laboratory applications.

Ammonium Hydroxide, 6.0 N Solution, is a solution of ammonia in water. Aqueous ammonia, as it's otherwise known is used as a complexant and base in qualitative inorganic analysis. It becomes a deep blue color with copper solutions. Used to dissolve silver oxide residues, such as the ones formed from Tollens' reagent, it is also commonly used in numerous cleaning agents, such as window cleaning formulas as well as a complexant that is manufactured to parts-per-billion trace impurities and has been used in the semiconductor industry to dissolve heavy or precious metal components.
