  • Analysis Of Calcium Hydroxide

    Evidence and Analysis: The literature Ksp for calcium hydroxide is 5.02×〖10〗^(-6), which is a relatively large Ksp value. This goes against the “rules of solubility” that labels calcium hydroxide as insoluble. According to the “rules of solubility”, calcium hydroxide should not be soluble in water; however, our results reveal that it does have some degree of solubility at standard conditions. We know this because we started with an initial concentration of calcium hydroxide and no concentration of either calcium or hydroxide ions. However, when this reaction reached equilibrium, we found a concentration of calcium hydroxide to be 1.1×〖10〗^(-2) M, concentration of calcium ions to be 1.3×〖10〗^(-2) M, and concentration of hydroxide ions to…

  • Separation Of Calcium Hydroxide

    Calcium hydroxide (Ca(OH)2), universally referred to as lime water or slaked lime is formed by reacting hydrated lime (calcium oxide, CaO) with water (H2O)[1] CaO (s) + H2O (l) ⇌ Ca(OH)2 (aq) (ΔHr = −63.7 kJ/mol of CaO) Calcium hydroxide is an economically favorable alkaline reagent to neutralize acid as it yields 2 moles of (OH)2 for every 1 mole of Ca(OH)2 (which is slightly soluble in water) when compared to sodium hydroxide [1] and it may separate from the solution ‘constant agitation must…

  • Hess's Law Lab Report

    used in research of other possible fuels by finding the cost to produce it and comparing it to the amount of energy it will provide to find out if it is a worthwhile investment. The main objectives of this lab are to find the energy changes in reactions two and three then using two and three find the ideal reaction one’s change in energy. The general experimental design is that using a calorimeter you would first find the change in energy of calcium carbonate reacting with two hydrochloric acid…

  • CSX Train Leakage Case Study

    freight train derailed causing a possible spill of the chemical contents it carried. According to the District of Columbia Fire and Emergency Medical Services department (DCFEMSD), the derailed train in northeastern Washington DC resulted in the leakage of hazardous chemical material by three cars (Washington, 2016). The total amount of cars sent outside the railroad in the derailment incident was however, confirmed to be 14 according to CSX. The possible extent of the hazardous spillage had not…

  • Fibrodysplasia Ossificans Progressiva Research Paper

    1. What is FOP? Fibrodysplasia Ossificans Progressiva is a rare genetic disease in which a person’s bones will begin to form into the muscles, tendons, ligaments, joints and connective tissues. Overtime the development will restrict a person’s movement. It has been described as turning a person into stone because their body is essentially encased by a second skeleton. 2. What are the initial symptoms? Symptoms of Fibrodysplasia Ossificans Progressiva, include: an infant being born with short,…

  • Essay On Osteoporosis

    I chose the topic of osteoporosis because it is a disease that almost every old person face after their bones wears down. Osteoporosis is when your bones do not have enough calcium and due to that the bones become brittle and weak. Old people and postmenopausal have the higher risk of getting this disease due to their bones getting older and weaker. Younger people wouldn’t have this problem if they ate enough calcium. Bones are an important part of your body because half of your body is bones…

  • Case Study: The Salter-Harris Classification

    The Salter-Harris classification is a radiologic classification system, developed in the 1960s, to describe fractures involving the growth plate in pediatric patients.1 It divides the fractures into five categories based on the extent of damage to the growth plate based on the mnemonic SALTER; type I: Slip or Separation of the growth plate, type II: Above the growth plate, type III: Lower than the growth plate, type IV: Through the growth plate, and type V: Raised epiphysis. Children have open…

  • Bone Remodeling

    Micro-fracture consolidation can be treated with bone remodeling, and the adaptation of skeleton is applied to “calcium homeostasis” and to mechanical use. The bone remodeling involves the bone resorption regarding to osteoclasts and bone formation relating to osteoblasts. Regular bone-related diseases including “bone-metastasized cancers”, Paget’s disease, multiple myeloma, and osteoporosis are caused by the disproportion between the resorption and formation processes. The increased…

  • Determining The Concentration Of Water Hardness

    Introduction Water hardness is defined as the sum of the concentrations of Ca2+ and Mg2+ in a water sample which is measured by amount of CaCO3. Typically, water hardness indicates the water quality, as hard water has greater concentrations of Ca2+ and Mg2+ and soft water has proportionally less concentrations of the aforementioned ions.1 Water that contains Ca2+ and Mg2+ concentrations above 100 milligrams per liter (mg/L) is categorized as hard while soft water contains ion concentrations…

  • Bone Loss Lab Report

    Introduction Determination of bone mineral density helps in assessing bone quality. For instance, loss of bone mass which is obtained clinically as the change in BDM (bone mineral density) aids in determining bone fragility (Paschalis, 2009). Though, bone mineral density cannot be used alone to indicate that someone will suffer from bone fracture since there is the difference in BDM between the populations. Some people in a particular community develop bone fracture while others do not. Some…
