objects known as “scum”. Calcium ions are typically the most common contributing factor for water hardness so this experiment uses CaCO3 (Calcium Carbonate) to analyze the hardness of an unknown sample. A scale of water hardness identifies “soft” water with a value less than 60 ppm (parts per million) and “hard” water with a value more than 200 ppm. 3 mL of ammonia/ammonium chloride buffer (pH 10) is added to the mixture prior to the titration to capture the calcium metal ions so the indicator

metal ions with a charge of +2 or higher. The ‘scum’ left over in a cleaned shower stall or coffee pot is equivalent to water hardness. Water dissolves salts which contains ions of sodium‚ magnesium‚ calcium‚ iron‚ and many other metal; however‚ the most prevalent ion found is calcium. Since calcium ions typically make the most predominant contribution to water hardness‚ by convention hardness is reported as mg 〖CaCo〗_3/L of solution. Water with a hardness value less than 60 ppm is considered “soft”

prevent osteoporosis depend on whether it is due to environmental factors‚ or genetics. Genetic form of osteoporosis cannot be prevented. However‚ you can decrease your risk by not being too skinny‚ because the bones deteriorate faster‚ consuming calcium‚ exercising and keeping a proper meal plan.

What is it? (Cause) Osteoporosis - a medical condition in which the bones become brittle and fragile from loss of tissue‚ typically as a result of hormonal changes‚ or deficiency of calcium or vitamin D. Osteoarthritis - degeneration of joint cartilage and the underlying bone‚ most common from middle age onward. It causes pain and stiffness‚ especially in the hip‚ knee‚ and thumb joints. Symptoms of… Osteoporosis • a loss of height as you age caused by compression in the spine or • experiencing

Osteoporosis Why is it a problem? Osteoporosis is a disease in which the bones become weak and are more likely to break. People with osteoporosis most often break bones in the hip‚ spine‚ and wrist. These issues result in the loss of bones which may change in some cases and not in others. How is it diagnosed? An accurate and common test done to diagnose osteoporosis is a bone density test to check a patient’s bone health. These tests diagnose the disease and tell whether you are likely to break

that develops as the individual ages. Secondary osteoporosis is related to an on other condition that places the individual at high risk of developing osteoporosis (Zamulko‚ 2015). These conditions could be linked to kidney function‚ liver function‚ calcium levels‚ thyroid and parathyroid problems‚ and phosphorus problems (Zamulko‚ 2015). The second problem related to bone health is osteopenia. Osteopenia is described by Dr. Zamulko (2015) as thinning of the bone. She further explained that osteopenia
