While cell membranes‚ heredity‚ gene expression‚ evolution‚ cellular metabolism‚ and chemical reactions are all appealing‚ water is undeniably more relevant. I decided to dissect the article entitled‚ “Water: The Science of Nature’s Most Important Nutrient” In this article Len Kravitz Ph.D. discusses the importance of water for human survival. The article does an excellent job of revealing

Hardness of Water by EDTA Titration Introduction Water hardness is caused by natural minerals that are dissolved into the water‚ predominantly calcium and magnesium‚ and is measured as the equivalent concentration of calcium carbonate (in milligrams per litre). Water hardness is usually noticed because of difficulty in lathering soap and the formation of a scum in the bathtub. Ca2+ and Mg2+ form insoluble salts with soaps causing precipitation of the soap scum. Another effect of hard water is “boiler

Aim: To compare the foaming capacities of five different commercial soaps. Apparatus: 5 test tubes‚ 5 conical flasks (100 ml)‚ test tube stand‚ Bunsen burner and stop watch. Materials Required: 5 different samples of soap and distilled water Theory: The foaming capacity of a soap sample depends upon the nature of soap and its concentration. This can be compared for various samples of soaps by taking the same concentration of solution and shaking them.The foam is formed and the time taken

Surface Water Pollution Freshwater makes up less than three percent of earth’s water‚ but is the source of virtually all drinking water.55 percent of that water comes from reservoirs‚ rivers‚ and lakes‚ These sources‚ called surface water‚ are vulnerable to pollution discharged out of pipes and precipitating out of the air but the primary source of their pollution today is runoff‚ pollutants washing off the land. These nonpoint or scattered sources are not easily traceable. fertilizers used

Water is an integral part of land/soil productivity. Its misuse can cause both degradation and erosion of soils. Management of water resource is considered to necessary for well being of human life as well as crop yields. There is a gap between the seasonal availability of water and its equitable supply throughout the year. Accordingly the storage of water and passage through soils is very important. It is well known that about 70% area in this country is subject to varying degree of water stress

As stated in the EMB report‚ domestic wastewater discharges contribute highest to the BOD load as the lack of sewage treatment system allows more than 90 percent of inadequately treated domestic sewage to be discharged into surface waters‚ which contain bacteria and viruses that threaten human life. Geographically‚ data show that one-third (30 percent) of BOD generation comes from Metro Manila and Region IV alone‚ at 18 and 15 percent‚ respectively (PEM‚ 2003). Industrial wastewater

fresh water is also becoming a scarcity. The limited availability of fresh water and its unequal distribution make water pollution a matter of great concern. Water pollution is generally localized and confined‚ making it more severe. The pollutants undergo many reactions and can become hazardous. 70 % of India’s fresh water is polluted‚ including several high altitude lakes. While water pollution is easier to study and manage‚ its control is highly complex and very costly. Water pollution
