Chemistry Of Natural Water :: essays research papers

The purpose of this experiment is to explore the herculeanness of the urine system on campus. Hard weewee hasbeen a problem for hundreds of years. One of theearlier references to the strainingness or softness ofwater is in Hippocrates discourse on water qualityin Fifth century B.C. Hard water causes manyproblems in both in the household and in theindustrial world. One of the largest problems with effortful water is that it tends to leave a end whenit evaporates. aside from being aestheticallyunpleasing to look at, the chassis up of hard waterresidue lowlife result in the clogging of valves, drainsand piping. This embodiment up is merely theaccumulation of the minerals dissolved in naturalwater and is commonly called scale. Other thanclogging plumbing, the build up of scale poses alarge problem in the industrial world. Many thingsthat are change are often cooled by water runningthru piping. The build up of scale in these pipescan greatly reduce the measurement of groove the coolingunit can draw away from the source it is stressful to inflame. This poses a potentially dangerous situation.The build up of excess heat can do a lot ofdamage boilers can explode, containers can meltetc. On the flip side of the coin, a build up of scaleon an object being heated, a eardrum for example,can greatly reduce the heat efficiency of the kettle.Because of this, it takes much more(prenominal) energy to heatthe kettle to the necessary temperature. In theindustrial world, this could amount to large sums ofmoney being thrown into wasted heat. In addendumto clogging plumbing and reducing heatingefficiency, the build up of hard water alsoadversely affects the efficiency of many scoop shovels andcleansers. The modestness for this is because hardwater contains many divalent or sometimes even multi-valued ions. These ions react with the soapand although they do not form precipitates, theyprevent the soap from doing its job. When thepolyvalent ions react with the soap, the y form aninsoluble soap scum. This is once over again quiteunpleasing to look at and stains many surfaces.The sole reason for all these problems arising fromhard water is because hard water tends to havehigher(prenominal) than normal concentrations of theseminerals, and hence it leaves a considerableamount more residue than normal water. Theconcentration of these minerals is what is knownas the waters Total Dissolved Solids or TDS forshort. This is merely a way of expressing howmany particles are dissolved in water. The TDSvary from waters of different sources, howeverthey are present in at least some quantity in all
