It is a measure of the acidity or basicity of the water. The scale runs from zero to 14. Zero is the most acidic. Seven is neutral biology chemistry general ocean physics their and 14 is the most basic. The pH scale is not linear, but logarithmic. A change of one pH unit, for example from seven to six, means that the water gets ten times more acidic.Due to its chemistry, salt water is able to absorb a certain amount of acidic matter without a resulting change in pH. The substances in the water that do this are called buffers. The ability to withstand changes in pH is called buffer capacity. Based on a method of measuring buffer capacity, it is referred to as the alkalinity of seawater. In some of the literature alkalinity is termed "carbonate hardness" or "kh carbonate buffer". This is exactly the same measurement as is measured in the Alkalinity Mini-Lab test.pH And AlkalinityThe pH of natural sea water varies geographically in the world's oceans between 8.1 biology chemistry general ocean physics their and 8.4. On a local scale the pH is however remarkably stable. This is due to the dissolved buffers (mainly bicarbonates), which prevent pH changes. Because of the enormous volume of the ocean, a nearly inexhaustible stock of buffers are present. The sea can take up large amounts of acids without a noticeable change in pH.Compared to the sea the volume of a marine aquarium is very limited biology chemistry general ocean physics their and therefore the alkalinity is also limited. As fish produce acid waste products biology chemistry general ocean physics their and as the buffering substances are used up by calcareous algae biology chemistry general ocean physics their and invertebrates, the buffer capacity may become so low that the pH could suddenly fall. This would be very dangerous to all organisms in the aquarium.The alkalinity is measured in so called milli-equivalents of alkaline substances (for example sodium bicarbonate) per liter. These alkaline substances have the power to prevent pH drops. The alkalinity of natural sea water is approximately 2.5 milli-equivalents per liter. This level should also be maintained in the marine aquarium.A common symptom of an unsuitable pH is pH stress. Especially in the marine aquarium, unsuitable pH values are very stressful to fish, biology chemistry general ocean physics their and increase the chance of the fish being susceptible to disease (marine white spot). To maintain a correct biology chemistry general ocean physics their and stable pH, check the pH biology chemistry general ocean physics their and alkalinity weekly.

General science - General science is the name of a class usually taught in United States high schools. It provides a brief overview of the scientific method, biology, physics, chemistry, and sometimes other subjects such as geology, astronomy, human physiology, or human health.
Degrees of freedom (physics and chemistry) - Degrees of freedom is a quite general term used in explaining dependence on parameters, and implying the possibility of counting the number of those parameters.
Neutron source - Neutron source is a general term referring to a variety devices that emit neutrons, irrespective of the mechanism used to produce the neutrons. Depending upon variables including the energy of the neutrons emitted by the source, the rate of neutrons emitted by the source, the size of the source, the cost of owning and maintaining the source, and government regulations related to the source, these devices find use in a diverse array of applications in areas of physics, engineering, medicine, nuclear weapons, petroleum exploration, biology, chemistry, nuclear power and other industries.
Physical Chemistry Chemical Physics - Physical Chemistry Chemical Physics (PCCP) is a scientific journal published since 1996 by the Royal Society of Chemistry on behalf of fourteen participating societies: the Deutsche Bunsen-Gesellschaft für Physikalische Chemie, Institute of Chemistry of Ireland, Israel Chemical Society, Kemisk Forening, Koninklijke Nederlandse Chemische ...
