Uses The highest value inorganic acid marketed in the U.S. and second in value to sulfuric acid. Used primarily for the preparation of salts used as fertilizers (ammonium and calcium salts), water softeners and detergents, animal feeds, and baking powder. Food-grade phosphoric acid is used to acidify soft drinks, e.g.. Coca Cola. Organic phosphates are used in flame retardants.

Describe the procedure of reverse osmosis for the purification of salt water for drinking water. 

Water can be obtained from salt water using this method. The solution is heated in the flask until it boils. The steam rises into the Liebig condenser, where it condenses back into water. The salt is left behind in the flask. In hot and arid countries such as Saudi Arabia this sort of technique is used on a much larger scale to obtain pure water for drinking (Figure 2.19). This process is carried out in a desalination plant. 

Even the water we drink contains some sodium but only about 1 percent of our total consumption. Obviously, we don t want to restrict our water drinking. Next, foods in their natural state, even fruits and vegetables and, more notably, dairy foods, provide about 12 percent of our salt intake. Surely, we don t want to eliminate any... 

Sesamin, the most abundant lignan present in sesame seed and sesame oil, was demonstrated to suppress the development of hypertension in rats induced by deoxycorticosterone acetate (DOCA) and salt (127). Dietary sesamin was also reported to effectively prevent the elevation of blood pressure and cardiac hypertrophy in two-kidney, one-clip (2k, Ic) renal hypertensive rats (128). In the stroke-prone spontaneously hypertensive rats (SHRSP), sesamin feeding was much more effective as an anti-hypertensive regimen in salt-loaded SHRSP (with 1% salt in drinking water) than in unloaded SHRSP (129). 

Drinking water is necessary for people, livestock, wildlife, crop irrigation, and for recreation. Although 70% of the Earth s surface is covered with water, most is salt water (salinity of 3.5%) and not fit to drink. Only 3% of the water on the Earth is freshwater (water that contains only minimal quantities of dissolved salts) and much of this water is in snow and ice (e.g., glaciers) as well as lakes, streams and groundwater. In some places in the world, freshwater is plentiful (e.g., the Great Lakes) however, in many places water is scarce. Wars have been fought over freshwater resources. 

Freshwater resources are precious and necessary for life. Work on cost-effective systems that can desalinate salt water for use as drinking water is ongoing and likely to be important to the future development of certain areas of the world. 

City water Drinking water from municipal facility. Often contains chlorine, a potential oxidant that can cause side-reactions. Inorganic salts and organic impurities may be present. 

Visit bookLmsscience.com for Web links to information about how salt is removed from salt water to provide drinking water. 

The best way to remove the water from the nitro is to let it sit in contact with a saturated salt solution. This sucks up water from the nitro in the same way that drinking salt water dehydrates shipwrecked sailors. Saturated salt solution is water that is holding dissolved in it all the salt (regular table salt) that it can. The best way to make saturated salt solution is start with hot water in any container, and add salt to it until no more will dissolve in it. Good stirring or shaking is essential to getting the maximum amount of salt to dissolve in the water. 

Robust statistics. Statistics which are less vulnerable to the presence of outliers and dirty data but which are generally slightly less efficient than the standard alternatives where the data are well behaved. The median, for example, is a robust statistic, whereas the mean is not. The mountain-bikes of the statistical world as opposed to its road-racers. A means to drink salt-water as if it were sweet. 

Turbulence due to river currents or a storm could move such a layer— and even entire shells—to shallower depths at which human contact could occur. All that layering would mean is that the chemical agent would be at the bottom. If the river current moved the layer downstream where sedimentation resulted in shallow water, human contact is conceivable. If the river flowed into the ocean where salinity causes the chemical agent s liquid density to be less than that of salt water, it could even rise to the surface. East, if the chemical agent enters a potable aquifer or a water intake downstream, ingestion is possible. CWM contamination is a problem in the Arabian Sea, where desalination provides most of the drinking water. 

Analysis of the composition of Earth s water supply underlines the scarcity of drinkable water worldwide 97% is salt water, 2% is frozen and only 1% is fresh water available for humans to drink. Over the last 50 years, the demand for drinkable water has increased by a factor of 4 to 4000 km /year, which corresponds to approximately 33% of the available water from rainfall (Meindersma et al, 2006).
