PH of neutrality is not exactly 7 (25 °C), although this is a good approximation in most cases. Neutrality is defined as the condition where [H] = [OH] (or the activities are equal). Since self-ionization of water holds the product of these concentration [H]×[OH] = K, it can be seen that at neutrality [H] = [OH] = , or pH = pK/2. pK is approximately 14 but depends on ionic strength and temperature, and so the pH of neutrality does also. Pure water and a solution of NaCl in pure water are both neutral, since dissociation of water produces equal numbers
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
