Gravimetric Determination of Calcium ABSTRACT Determining the mass of a pure compound is a method of a gravimetric analysis. One of the gravimetric analyses is the precipitation; it is a method of separating the analyte from the unknown sample as a precipitate where it will be filtered and converted into a known composition that can be weighed to determine its mass (Skoog et al‚ 2013). Determining the mass of calcium by using gravimetric analysis was the objective of the experiment. A 25 mL

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

Writing Oct.3th 2012 Self Self is awareness that a person individual for his own whole existence produced the kind of self-consciousness. And philosophers give it more profound definition. It can be a character‚ a hobby or an opinion. Everyone has a unique self; like selflessly‚ selfish‚ self-abased or self-conceited. Everyone acts different character in his or her life. It all depends on people’s mind. If you want to be what kind of person‚ then you will be. Self is personal and independent

Serina Pooja Sowman | Practical 7: Determination of Hardness in Water | | | | | 10/3/2012 | | Aim: To determine the different types of hardness and alkalinity found in the water by titration methods. This is used to calculate the concentrations of calcium and magnesium found in the water. Principles: The hardness of water is determined to provide a measure of the quality of water for household and industrial use. Hard water is not a health hazard. Drinking hard water

Brain Death Determination When the brain has a lack of oxygen‚ even for a few minutes‚ it could lead to loss of brain functions such as a gradual loss level of consciousness or a complete loss of consciousness causing the person to slip into a coma. In the most profound cases‚ irreversible brain damage and death occurs. Oxygen deficiency can by caused by many things‚ such as; a brain injury‚ fall from height‚ traffic accidents‚ heart failure‚ stroke or some neurological disease. That may cause

Report of Density Determinations Density is defined as the mass of substance per unit volume. Both pure substances and solutions are applicable. Today we are going to determine the Density of rock chunks and NaCl solution. In this experiment‚ we will determine the mass and volume of each object and then we will calculate the ratio—the density. In the first part of the experiment‚ we should measure the density of some irregularly shaped chunks of rock. The Weight of rocks is 18.769g
