57028-96-3 / 25% Poly Ammonia 25 Solution Solution PHMG

Industrial Cleaning and Degreasing: Ammonia solution with a concentration of 25% is used in industrial settings for cleaning and degreasing metal surfaces, removing scale and rust, and preparing surfaces for painting or coating. It is often applied as a solution or in combination with other cleaning agents for enhanced performance.

Laboratory Reagent: In laboratories, ammonia solution at 25% concentration is utilized as a reagent for various analytical and experimental purposes. It may be employed in chemical reactions, titrations, and pH adjustments, as well as in qualitative and quantitative analysis methods.

Textile Processing: In the textile industry, ammonia solution with a concentration of 25% is used for processes such as dyeing, printing, and finishing of fabrics. It helps fix dyes to fibers, adjust pH levels in dye baths, and remove excess dyes or impurities from textile materials.

Water Treatment: Ammonia solution at 25% concentration can be employed in water treatment processes for pH adjustment, where it is used to raise the pH of acidic water to a more neutral or alkaline level. It may also be utilized for chloramine disinfection, where it reacts with chlorine to form monochloramine, a less reactive disinfectant for water treatment.

Chemical Synthesis: Ammonia solution at 25% concentration serves as a precursor or reagent in various chemical synthesis reactions for the production of other chemicals and compounds. It may be used as a source of ammonia in organic synthesis, pharmaceutical manufacturing, and chemical processing industries.

Chemical Composition: Ammonia solution 25% consists of ammonia gas dissolved in water. Chemically, it is represented as NH3(aq) and contains ammonium hydroxide molecules.

Concentration: The concentration of ammonia in a 25% solution means that for every 100 grams of solution, 25 grams are ammonia.

pH: Ammonia solution 25% is alkaline in nature, with a pH typically ranging from around 11 to 13. The presence of ammonium hydroxide makes it a weak base.

Appearance: Ammonia solution 25% appears as a clear, colorless liquid. It has a pungent odor characteristic of ammonia, which becomes more pronounced with increasing concentration.

Solubility: Ammonia gas is highly soluble in water, and at equilibrium, a 25% solution can contain a significant amount of dissolved ammonia.
