Water intoxication. Water intoxication, also known as water poisoning, hyperhydration, overhydration or water toxemia is a potentially fatal disturbance in brain functions that can result when the normal balance of electrolytes in the body is pushed outside safe limits by excessive water intake. Under normal circumstances, accidentally ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Thermodynamics. [edit] The electrolysis of water in standard conditions requires a theoretical minimum of 237 kJ of electrical energy input to dissociate each mole of water, which is the standard Gibbs free energyof formation of water. It also requires thermal energy to balance the change in entropy of the reaction.
Water softening. Idealized image of water softening process involving replacement of calcium ions in water with sodium ions donated by a cation-exchange resin. Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is ...
An action adventure video game released by Activision called How to Train Your Dragon was released for the Wii, Xbox 360, and PS3 gaming consoles. It is loosely based on the film and was released on March 23, 2010. A game for Nintendo DS published by Griptonite Games, was also released on March 23, 2010 and published by Activision.
Cut back on salt. Reducing sodium intake is one of the first steps the experts recommend to lose water weight. The Dietary Guidelines for Americans recommend limiting sodium intake to 2,300 ...
The refractive index of water at 20 °C for visible light is 1.33. [1] The refractive index of normal ice is 1.31 (from List of refractive indices ). In general, an index of refraction is a complex number with real and imaginary parts, where the latter indicates the strength of absorption loss at a particular wavelength.
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, as they are highly reducing in nature. [2] Notable examples include alkali metals, lithium through caesium, and alkaline earth metals, magnesium through barium . Some water-reactive substances are also pyrophoric, like organometallics and sulfuric ...
