    Water is a tasteless odorless vital element in which 90 percent of all organisms depend on to survive. It is one of the best-known ionizing agents and, is frequently called the universal solvent. Water combines with certain salts to form hydrates. It reacts with metal oxides to form acids and it also acts as a catalyst in many important chemical reactions. Not only is it essential to our health, but it is also crucial in the household and the industrial world. Every day we use water for cooking...

    Solutions & Solubility Pure water, which is an odour less, colorless, and tasteless substance is often called the universal solvent. As water moves through soil, it dissolves very small amounts of minerals such as calcium and magnesium. The greater the content of calcium and magnesium, the more hard the water is. Therefore, hard water is the result of an excess of two elements, C and Mg. The hardness of water is measured in grains per gallon (gig), milligrams per litre (mg / l ) or parts per mi...

    The purpose of this experiment is to explore the hardness of the water on campus. Hard water has been a problem for hundreds of years. One of the earliest references to the hardness or softness of water is in Hippocrates discourse on water quality in Fifth century B. C. Hard water causes many problems in both in the household and in the industrial world. One of the largest problems with hard water is that it tends to leave a residue when it evaporates. Aside from being aesthetically unpleasing ...

    INTRODUCTION: Water that contains calcium and magnesium ions is called "hard water" because calcium and magnesium ions can combine with other ions and compounds to leave a hard scale on the surfaces they touch. Hard water may be a troublesome in household water supplies. Fortunately, there are simple solutions to hard water problems. Hard water can be softened by the removal of metallic ions responsible for the hardness. This is known as water softening. Softened water is desirable in the bathtu...
