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

From a chemical perspective‚ what is oxygen? Identify its atomic number‚ the group it fits into OXYGEN in the periodic table‚ its chemical formula‚ its melting point‚ boiling point and state at room temperature. Oxygen is highly reactive‚ nonmetal‚ oxidising agent that readily forms oxides‚ it is an element. By mass‚ oxygen is the third-most abundant element after hydrogen and helium. The Atomic Number: 8 Group: The chalcogen group Chemical formula: 02 Melting

Breathing is a critical component of respiration‚ a process in which life sustaining oxygen is delivered to all the cells in the body and carbon dioxide is removed and released into the air. Breathing difficulties are symptoms of a variety of mild to serious underlying disorders‚ diseases and conditions that interfere with normal respiration and breathing. Hence‚ the ability to carry out and document a full respiratory assessment is an essential skill for all nurses. While conducting the assessment

What is water purification? Water purification generally means freeing water from any kind of impurity it contains‚ such as contaminants or micro organisms. Water purification is not a very one-sided process; the purification process contains many steps. The steps that need to be progressed depend on the kind of impurities that are found in the water. This can differ very much for different types of water. In which ways is polluted water treated? Settling Before the purification process begins some

Importance of Water All living things need water. The Earth is full of water. Water is the most essential element‚ next to air‚ to our survival. Water makes up more than two thirds of the weight of the human body‚ and without it‚ we would die in a few days. There are many water importances in our life to complete daily life and to maintain we body health. Humans and other creatures must drink water to avoid dehydration. Dehydration is defined as a loss or insufficient levels of water and important

Importance of Water Water is important to the mechanics of the human body. The body cannot work without it‚ just as a car cannot run without gas and oil. In fact‚ all the cell and organ functions that make up our entire anatomy and physiology depend on water for their functioning. Water serves as a lubricant in digestion and almost all other body processes. The water in our saliva helps facilitate chewing and swallowing‚ ensuring that food will slide easily downs the esophagus. Water also lubricates

What is Alkaline Water? Alkaline water‚ also commonly known as ionized water‚ is water that has a pH level greater than seven. This water is generally produced with the aid of a faucet-based water ionizer‚ or "alkalizer" and features a number of health benefits. Making Alkaline Water These are some of the possible sources of alkaline water: * Lemon (& Lime) Water * pH Drops * Alkalising Powder * Mainstream Water Filters * Water Distillers * Reverse Osmosis * Alkaline

Brittany Roberts AP bio WATER ESSAY The first thing water reminds us of is the clear liquid in our water bottles. However‚ water is more than a normal substance. Water is the beginning and the continual of life on earth. Because of its many unique properties‚ water was able to start life on our planet. Water covers about 3/4 of the earth. In nature‚ water naturally exists in all three physical states of matter—solid‚ liquid and gas. Water’s extraordinary properties are emergent properties resulting
