Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Goods are capable of being physically delivered to a consumer. Goods that are economic intangibles can only be stored, delivered, and consumed by means of media. Goods, both tangibles and intangibles, may involve the transfer of product ownership to the consumer. Services do not normally involve transfer of ownership of the service itself, but ...
For example, a restaurant provides a physical good (prepared food), but also provides services in the form of ambience, the setting and clearing of the table, etc. Although some utilities, such as electricity and communications service providers, exclusively provide services, other utilities deliver physical goods, such as water utilities.

[6] A typical example is the machinery used in a factory. At the macroeconomic level, "the nation's capital stock includes buildings, equipment, software, and inventories during a ...
Much of chemistry research is focused on the synthesis and characterization of beneficial products, as well as the detection and removal of undesirable products. Synthetic chemists can be subdivided into research chemists who design new chemicals and pioneer new methods for synthesizing chemicals, as well as process chemists who scale up chemical production and make it safer, more ...
Where goods are sold or supplied by reference to a sample, relevant sale of goods legislation may dictate the supplier's legal obligations in ensuring that the bulk of the goods corresponds with the goods comprising the sample, for example in the UK, the Sale of Goods Act 1979, section 15, [8] the Supply of Goods and Services Act 1982, section ...
Some chemical substances can be combined or converted into new substances by means of chemical reactions. Chemicals that do not possess this ability are said to be inert. Pure water is an example of a chemical substance, with a constant composition of two hydrogen atoms bonded to a single oxygen atom (i.e. H 2 O).
The emergence of India as a manufacturer and supplier of speciality chemicals has had a major impact on the Global speciality chemical industry. In India the many speciality chemical companies are members of national organisations such as the Indian Chemical Council (ICC) and the Indian Speciality Chemical Manufacturers' Association (ISCMA).
