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

An experiment to investigate the effect of temperature on the rate of reaction of the Enzyme Trypsin. Aim: This investigation was on the effect temperature has on the rate that the enzyme trypsin hydrolyses its substrate‚ a protein found in milk (casein). This investigation was conducted under controlled conditions‚ the temperature being the changeable variable. Trypsin and its substrate (powdered milk which is a source of the protein casein) were heated in a water bath. The contents of the two tubes

In our lab‚ we were given the task of burning seven different salts and taking notes of what we observed. The different salts included Potassium chloride‚ Calcium chloride‚ Strontium chloride‚ Lithium chloride‚ Copper II chloride‚ Sodium Chloride‚ and Barium Chloride. Burning a pinch of each salt separately by holding a nichrome wire over a Bunsen burner‚ we found that each salt emitted a different color of light. For example‚ Potassium Chloride burnt a bright pink flame when burned‚ while Calcium

The Effects of Snails and Elodea in Water on Carbon Dioxide Levels Problem: How does varying the type of organism (plant or animal) in the level affect the level of carbon dioxide? Background: This lab is used to test the effect the respiration rates in plants in animals and how it affects the level of carbon dioxide present in the water. Oxygen and carbon dioxide are gases that are vital to all organisms‚ whether it is given or released through that organism. Both plants and animals
