    Properties of Water Introduction: Water’s chemical description is H2O. As the diagram to the left shows‚ that is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom‚ resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side‚ where the oxygen atom is. This uneven distribution of charge is called polarity. Since opposite electrical charges attract‚ water molecules

    Cause and Effects of Water Pollution Water is a key resource on our planet and is undervalued by humans causing water pollution. Water makes up 70% of the earth and 60% of the human body‚ therefore the pollution of water is in need to come to an end because it is essential to all living aspects on earth ("Causes and Effects of Water Pollution…"). Water pollution is typically caused by littering‚ industrial waste‚ oil pollution‚ and primarily‚ by the human carelessness. It needs to be taken more

    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 Cycle

    • 417 Words
    • 2 Pages

    Water Cycle Earth’s water is always in movement‚ and the water cycle‚ also known as the hydrologic cycle‚ describes the continuous movement of water on‚ above‚ and below the surface of the Earth. Since the water cycle is truly a "cycle‚" there is no beginning or end. Water can change states among liquid‚ vapor‚ and ice at various places in the water cycle‚ with these processes happening in the blink of an eye and over millions of years. Although the balance of water on Earth remains fairly constant

    The Polarity of Water

    • 661 Words
    • 3 Pages

    The polarity of water Polarity means that the molecule has both a positively and negatively charged end. More important‚ the polarity of water is responsible for effectively dissolving other polar molecules‚ such as sugars and ionic compounds such as salt. Ionic compounds dissolve in water to form ions. This is important to remember because for most biological reactions to occur‚ the reactants must be dissolved in water. Because water is able to dissolve so many common substances‚ it is known as
