Ammonium Hydroxide, Reagent, ACS is a solution of amonia in water. Aqueous amonia, 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. Also used to dissolve silver oxide residues, such as the ones formed from Tollens' reagent. It is also commmonly used in numerous household cleaning agents, such as window cleaning formula. As an ACS grade Reagent, Spectrum Chemical manufactured Ammonium Hydroxide is used as the quality standard against which other substances are graded and has met the toughest regulatory standards for quality and purity.

Aluminum Nitrate, Nonahydrate, Crystal, Reagent, ACS is a strong oxidizing agent. It is a salt of aluminum and nitric acid existing normally as a crystalline hydrate. Aluminum nitrate has many different uses including extracting uranium, petroleum refining, as a nitrating agent, and in tanning leather. As an ACS grade quality reagent, its chemical specifications are the de facto standards for chemicals used in many high-purity applications and typically designate the highest quality chemical available for laboratory use. Spectrum Chemical manufactured Reagent ACS grade products meet the toughest regulatory standards for quality and purity.
