Procedure: Melting point of RCO2H Before observing the melting point of the unknown sample‚ the melting apparatus had to be standardized with a standard substance having the melting point of 151°C-153°C. After placing a small sample of the standard in a capillary tube and inserting the tube into the sample tube holder‚ the plateau on the device was set to 15°C below the expected melting point. After its temperature reached the plateau‚ the temperature increment was set at 1°C per minute‚ and the

Quantitative Studies on Medication Adherence Maleah Perdue University of South Alabama Introduction Medication adherence is a significant issue in the health systems of today. Low medication adherence can unnecessarily increase cost of health care and the amount of admissions. According to Conn et al.‚ inadequate medication adherence may account for up to 10% of older adult hospital admissions and may cause up to $100 billion in annual health care cost (2009). Increased medication adherence

Complexometric Determination of Water Hardness Lab Report Introduction: In this lab the use of disodium salt of EDTA is used to determine the concentration of M^2+ metal ion impurities in hard water by chelometric titration. The indicator Eriochrome Black T will help detect when you EDTA has completely chelated the metal impurities. Chemical Principle: A complex ion consists of a metal ion with Lewis bases attached to it. These Bases form strong covalent bonds with the central complex
