What is pure water?

Some articles on pure water, water:

Electrolysis Of Water - Electrolyte Selection
... If the above described processes occur in pure water, H+ cations will accumulate at the anode and OH− anions will accumulate at the cathode ... This can be verified by adding a pH indicator to the water the water near the anode is acidic while the water near the cathode is basic ... ions that approach the anode mostly combine with the positive hydronium ions (H3O+) to form water ...
Cytosol - Properties and Composition - Water
... Most of the cytosol is water, which makes up about 70% of the total volume of a typical cell ... The viscosity of cytoplasm is roughly the same as pure water, although diffusion of small molecules through this liquid is about fourfold slower than in pure water, due mostly to collisions with the ... Studies in the brine shrimp have examined how water affects cell functions these saw that a 20% reduction in the amount of water in a cell inhibits ...
Temperature-responsive Polymer - Examples of Thermoresponsive Polymers - Thermoresponsivity in Water
... Polymer solutions that show thermoresponsivity in water are especially important since water as a solvent is cheap, safe and biologically relevant ... Current research efforts focus on water-based applications like drug delivey systems, tissue engineering, bioseparation (see the section Applications) ... Numerous polymers with LCST in water are known ...
Other Water Purification Techniques
... Other popular methods for purifying water, especially for local private supplies are listed below ... Boiling Water is heated hot enough and long enough to inactivate or kill micro-organisms that normally live in water at room temperature ... In areas where the water is "hard" (that is, containing significant dissolved calcium salts), boiling decomposes the bicarbonate ions, resulting in partial ...
Water Potential
... Water potential is the potential energy of water per unit volume relative to pure water in reference conditions ... Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure, or matrix effects such as surface tension ... Water potential has proved especially useful in understanding water movement within plants, animals, and soil ...

Famous quotes containing the words water and/or pure:

    Camels are snobbish
    and sheep, unintelligent; water buffaloes, neurasthenic—
    even murderous.
    Reindeer seem over-serious.
    Marianne Moore (1887–1972)

    There are certain books in the world which every searcher for truth must know: the Bible, the Critique of Pure Reason, the Origin of Species, and Karl Marx’s Capital.
