Water Technology Hardness of Water: Natural waters containing large quantities of dissolved salts of Calcium (Ca) & Magnesium (Mg) is called hard water. It is a characteristic of preventing lather formation of water with soap. Ca2+ & Mg2+ ions react with soaps which are salts of fatty acids (stearic or palmitic acid) to give insoluble scums or precipitates of calcium or magnesium stearate or palmitate. 2C17H35COO- + Ca2+ → (C17H35COO)2 Ca (scum) 2C17H35COO- + Mg2+ → (C17H35COO)2

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

EXPERIMENT 1: WATER CRYSTALIZATION OBJECTIVES: To determine the percentage of water in aluminium sulphate hydrate To calculate the water of crystallization for aluminium sulphate hydrate To prove that a hydrate solution will lose some of it mass after heated INTRODUCTION A hydrated salt is a crystallize salt molecule that is weakly attached to a certain number of water molecules. Salt is created when an acid’s anion (negative ions) and a base’s cation (positive ions) are combined to produce

researching for this essay explaining what soil and water conservation means to me‚ I found two quotes that really stuck out to me. One written by Franklin D. Roosevelt stated‚ “A nation that destroys its soils destroys itself. Forests are the lungs of our land‚ purifying the air and giving fresh strength to our people.”‚ and another that was written by an unknown author read‚ “Water is life’s mater and matrix‚ mother and medium.
