Ammonia solution is a solution of ammonia (NH3) gas dissolved in water. It is a clear, colorless liquid with a pungent odor and a basic pH. The concentration of ammonia in the solution can vary, and is typically expressed in terms of percent by weight or by volume. Ammonia solutions are commonly used in a variety of applications, including cleaning agents, fertilizers, and as a precursor to other chemicals. They are also used in industrial processes such as refrigeration, gas purification, and water treatment. Ammonia solutions can be dangerous if not handled properly, as they are highly corrosive and can release toxic fumes if mixed with certain chemicals

Methyl ethyl ketone (MEK) is a colorless, flammable liquid organic compound with the chemical formula C4H8O. It is a ketone, which means it contains a carbonyl group (C=O) bonded to two carbon atoms. MEK has a sweet, pungent odor and is commonly used as a solvent in various industrial applications such as coatings, adhesives, and printing inks. It can also be used as a chemical intermediate in the production of other chemicals. MEK is highly volatile and can pose health hazards if not handled properly.
