An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule or ion able to accept a hydrogen ion from an acid. Acidic substances are usually identified by their sour taste.
An acid is a molecule or ion capable of donating a proton (hydrogen ion H+) (a Brønsted–Lowry acid), or, alternatively, capable of forming a covalent bond with an electron pair (a Lewis acid). The first category of acids are the proton donors, or Brønsted–Lowry acids.
Chemical additives and agents include a wide range of materials added to polymer resins, paints and coatings, adhesives, and other substances to modify specific processing or end-use properties.
Fine chemicals are complex, single, pure chemical substances, produced in limited quantities in multipurpose plants by multistep batch chemical or biotechnological processes. ... The industry is fragmented and extends from small, privately owned companies to divisions of big, diversified chemical enterprises.
Generally, a clinical laboratory or medical laboratory is a place where tests are performed on clinical specimens (also known as a patient sample), such as blood or urine, and the results analyzed. ... Laboratory testing can be extremely important in determining what is wrong (or not wrong) with an individual patient.
Pharmaceutical chemicals are specially designed to act on living cells which is presents a special risk when they enter, persist and disseminate in the environment. Chemical processes are used to produce chemical products and are by definition processes which include chemical alteration.
Pharmaceutical chemistry is the study of drugs, and it involves drug development. This includes drug discovery, delivery, absorption, metabolism, and more. There are elements of biomedical analysis, pharmacology, pharmacokinetics, and pharmacodynamics. Pharmaceutical chemistry work is usually done in a lab setting.
Paints and allied products manufacturing operations include the production of paints, inks, adhesives, stains, varnishes, shellacs, putties, sealers, caulks, and other coatings from raw materials, the intended use of which is to leave a dried film of solid material on a substrate.
The substances that are removed during the water treatment process are suspended solids, viruses, fungi, bacteria, algae, and minerals. The process involves both physical and chemical methods. The chemical used in this process are called water treatment chemicals.
Chemicals that are used are for instance sodium chloride, potassium chloride, citric acid and chlorine dioxide. Chlorine dioxide cleansing serves the removal of organic contaminants on ion exchange resins. Prior to every cleaning treatment resins should be regenerated.
Dye Intermediates are organic compounds or mixtures and petroleum downstream products that are further synthesized for applications in textiles, paints, plastics, paper, printing inks, leather. ... They also serve as a vital raw material for Acid, Direct and Reactive Dyes. It is very significant to protect these chemicals.
Agrochemicals are pesticides, herbicides, or fertilizers used for the management of ecosystems in agricultural sectors. ... However, it is estimated that up to 40% of the world's crops are spoiled by plant pests and diseases – even with the effective implementation of pesticides. Agriculture chemicals, or agrochemicals for short, most commonly refers to pesticides and fertilizers, which are used in agriculture to control insects and weeds, prevent diseases as well as promote plant growth. Some examples of agrochemicals include pesticides, herbicides, insecticides, and fungicides.
A pigment is a colored material that is completely or nearly insoluble in water. In contrast, dyes are typically soluble, at least at some stage in their use. Generally dyes are often organic compounds whereas pigments are often inorganic compounds.
