PH the Hammett acidity function, "H", has been developed in connection with superacids. The concept of "unified pH scale" has been developed on the basis of the absolute chemical potential of the proton. This model uses the Lewis acid–base definition. This scale applies to liquids, gases and even solids. In 2010, a new "unified absolute pH scale" has been proposed that would allow various pH ranges across different solutions to use a common proton reference standard. Pure water is neutral. When an acid is dissolved in water, the pH will be less than 7 (25 °C). When a base, or alkali,
Ortek Therapeutics Ortek Therapeutics Ortek Therapeutics, Inc. is a private healthcare company based in Roslyn Heights, New York which specializes in researching and commercializing oral care products. It was founded in 1998. To date, Ortek's commercial success is based on the company's patented AlkaGen Technology (an arginine bicarbonate/calcium carbonate complex). The Company plans on incorporating this technology in their sugarless soft chews, BasicBites. Arginine is a common amino acid found in many foods and is also naturally found in saliva. On tooth surfaces, arginine is broken down by certain pH rising plaque bacteria to acid-neutralizing alkali. This results in a sustained neutral
