because the bone is largely made up of calcium salts. The vinegar broke the calcium phosphate down‚ leaving only collagen left. As we learned collagen is flexible so this made the bone bended easily. Calcium gives bone its strength and durability. Each time I changed the vinegar I was dumping the extracted calcium out. This shows how much of an important role calcium plays‚ without it bones would be flimsy. It also reveals how the structure of bone‚ having calcium‚ allows it to function properly for

5. Calcite A Report By: Shameka King December 4‚ 2012 SEN 1 Mr. Bibula 2. Calcite was discovered in 1852 by a mineralogist by the name of John P. Calcite. Calcite is a carbonate mineral that is usually white or colorless‚ but can have variety of colors due to impurities. It is one of the world’s most important minerals and is the most common. Calcite is one of the softest minerals and can be found in sedimentary and metamorphic rocks

Calcinosis cutis is rare condition signified by calcium deposition in skin and subcutaneous tissues. In all cases of calcinosis cutis‚ insoluble compounds of calcium are deposited within the skin due to local and/or systemic factors. These calcium salts consist primarily of hydroxyapatite crystals or amorphous calcium phosphate. It is commonly seen in blacks‚ and no apparent gender predilection is noted (6‚7) From the pathogenesis point of view‚ the condition is classified as metastatic‚ dystrophic

swirl‚ dip a toothpick with water and thenn into the EDTA indicator powder. Then swirl the toothpick into the beaker Observation and Data Table: By finding the total hardness‚ I was analyzing the water sample for the combined concentration of calcium and magnesium ions. When making the buffer‚ the sample turned blue‚ allowing me to get a sense of what color I would be looking for later on in the experiment. I tested my tap water for the total hardness by adding EDTA solution through a titrator

Hard Water How can water be hard? Well‚ it can‚ but maybe not in the sense that one would think. Hard water refers to water with dissolved calcium and magnesium ions in it. Rainwater is naturally soft‚ but when the water runs through the ground or over rocks causing erosion‚ calcium and magnesium ions can be easily picked up. Most people prefer hard water to soft water for drinking‚ because the ions are good for you‚ and because soft water leaves a “dry” taste in one’s mouth (1‚2). Big businesses

using complexometric titration the hardness of a sample of water can be obtained. Methods To begin‚ a solution of 500 mL of disodium EDTA with a mean M of 0.00412 was prepared. Next‚ the disodium EDTA solution was standardized using 10.18 mL calcium ion stock solution (1.000g/CaCO3)‚ ammonia/ammonium chloride buffer‚ and Eriochrome Black T as an indicator. Then‚ using the standardized disodium EDTA solution‚ an unknown sample (#94) was titrated. Finally‚ the results were compared with that

chemicals that get involved and added into the water as it travels. This relates to the hardness of water. The hardness of water is basically caused by the amounts of charged minerals in water. The two most significant ones are magnesium (Mg2+) and calcium (Ca2+)(1). Water is an excellent solvent and therefore easily picks up

powerful water softener that stands up to its reputation‚ being a great choice when it comes to meeting a small family need. As you already know‚ the water that you receive in your home is hard water because it contains a lot of minerals‚ including calcium and magnesium. As such‚ using hard water in your home‚ will make you plenty of problems such as ugly stains on tubs and sinks. Since water appliances are forced to work harder‚ there will be higher water bills‚ as well. However‚ water softening devices
