Introduction In order to determine the content of calcium and magnesium in an unknown sample of limestone‚ the utilization of atomic absorption spectrophotometry can help in deciphering the unknown concentrations of each molecule in the limestone sample. Atomic absorption spectrophotometry‚ emits radiation of the correct frequency that is passed through a flame and the intensity of the transmitted radiation is measured¹.The calcium concentration or ppm can be measured using the absorbance of the

Why Calcium nutrition is so important? Calcium is one of the most important minerals that body needs in order to function properly and to maintain optimal health‚ especially when it comes to bone. Calcium is used in so many ways throughout the body. It is necessary for contracting muscles‚ forming and strengthening bones and teeth‚ conducting nerve impulses throughout the body‚ blood clotting‚ maintaining a normal heart beat as well as other important processes. Calcium performs a number of basic
Premium Bone Nutrition Calcium
Calcium is an extremely important factor for health and longevity. It serves both a structural and physiological role in the entire organism. Bones are constantly breaking down and rebuilding‚ and calcium is directly involved in this process. Calcium ions (Ca2+) are essential mediators of a wide variety of cellular activities‚ including the passing of information along neurons and between adjacent neurons. Hormonal regulation is also mediated by the proper functions of calcium and calcium ions

a difference in the amount of calcium carbonate in brown versus white chicken eggs. Background: Calcium carbonate (CaCO3) is a component of seashells and eggshells that gives them their strength and hardness. Because calcium carbonate is a base‚ it will react with acids to form a salt and water. The complete reaction of calcium carbonate with hydrochloric acid is: CaCO3 (s) + HCl (aq) ( CaCl2 (aq) + CO2 (g) + H2O (l) The portion of the shell that is not calcium carbonate does not react with

The solubility of calcium hydroxide Aim: to find out the solubility of a substance that only partially dissolves in water. Method: place about 100cm3 of distilled water in a flask and add about one spatula of solid calcium hydroxide. Stopper the flask and shake well for one minute. Leave to stand for at least 24 hours. Titrate 10cm3 samples against 0.05 mol dm-3 hydrochloric acid solution using methyl orange as an indicator. Obtain enough results to calculate an accurate average‚ and then
