纯净水和矿泉水的区别（The difference between pure water and mineral water） The difference between pure water and mineral water Reward points: 10 - solve the time: 2008-7-30 16:21 Whats the difference between pure water and mineral water? I often feel so bad with pure water. That kind of water is more beneficial to the human body. Questioner: david_yi2000 - first class best answer, pure water, as the name suggests, is pure water, almost free of impurities. One important measure of pure water is conductivity (the conductivity of water). The water contains more impurities, its conductivity is greater (H + and oh - ionized water itself can make water conductive). Distilled water, as we often say, is pure water made by distillation. Drinking water: refers to conform to the hygienic standards for drinking water as raw water by distillation, deionization, ion exchange, reverse osmosis and other appropriate processing methods, removal of minerals, organic ingredients, harmful impurities and microorganisms are prepared, without any additives (except for ozone) can direct drinking water. Mineral water is minerals containing water, which contains the body must be rare elements. Generally speaking, mineral water is often distinguished from ordinary fresh water from temperature, salt composition, salinity, water quality, chemical composition, or the characteristics of free escaping gases. Chinas national standard stipulated in drinking natural mineral water is gushing from deep underground natural or artificial mining, uncontaminated groundwater; mineral salt, contain a certain amount of trace elements or carbon dioxide; in general, the chemical composition, flow rate and water temperature is relatively stable in the natural dynamic range. The trace elements in mineral water can participate in the bodys hormones, nucleic acid metabolism, it should be said that the health component of human needs, but the research on physiological chemistry after the results show that: there are many minera
