Gravimetric Analysis of CA2+ as CaC2O4.H2O Introduction Weight determination represents one of the most accurate and precise form of measurement carried out in lab analysis. Thus‚ gravimetric analysis provides a great assay of a variety of analytes. Mixtures of compounds in difference phases provide us with one of the simplest methods of separation and mass explorations. Separating a solid mass from a liquid involves the commonplace

Copper sulphate experiment Introduction There are a number of different methods of making salts‚ such as the reaction of a metal with an acid. Copper metal‚ however‚ does not react with sulphuric acid and so another method must be used. In this experiment a basic copper compound (copper(II) oxide) will be reacted with sulphuric acid giving copper(II) sulphate as one of the products. Method 1. Wear goggles and keep your face away from the beaker during the reaction 2. Place 20 cmm3 sulphuric

Gravimetric Analysis of a Chloride Salt CHEM 1001 Purpose: To illustrate typical techniques used in gravimetric analysis by determining quantitatively the chloride content in an unknown soluble salt. Theory: AgCl(s) is a very insoluble solid‚ yet still does have some solubility. Because of these traits‚ the following reaction is able to occur: Ag+(aq) + Cl−(aq) → AgCl(s) . This reaction is able to occur in both directions. When a soluble silver salt such as AgNO3 is added to a solution containing

final project entails systematic extraction of decision-aiding insights out of a dataset. The project will provide hands-on experience in conducting and interpreting different types of function-wise statistical analysis. The focus of the analysis will be on marketing strategies and analysis-related topics (South University Online‚ 2012). The sample set was examined thoroughly to reveal findings relevant to the marketing strategies and the interpretation of the data. The median income is between
