Exercise 14: Qualitative Anion Tests PURPOSE: The purpose of this experiment is to identify some commonly occurring anions & to study some of the reactions used for their identification. PROCEDURE: You must first determine to which of the three groups the various anions belong. Since no two people observe the same event in exactly the same way it is important to also conduct specific confirmation tests on the known samples of each anion. This information will help identify the anion

Abstract The present research paper investigates the IT application of collaborative planning‚ forecasting and replenishment (CPFR). The first part of the paper sets a theoretical framework which initially defines the software use and implementation‚ and then recognizes the key advantages of this particular software. Moreover‚ to be fairly critical some major pitfalls identified by academics and practitioners are also presented. At the end it is up to the individual organization to make their

Qualitative Analysis of Cations Short Overview The most common cations have been placed into five groups based upon solubility in aqueous solutions when different reagents are added. The reactions which occur are useful in identifying the presence of these cations in unknown samples. The process of identifying the cations is called qualitative analysis. The purpose of this experiment is to identify which cations are present in unknown solutions. A data sheet was not prepared for this experiment

Simple qualitative analysis involves the identification of the constituents of an inorganic substance or a mixture of substances. The inorganic substances are split-up into two types of charged particles one of which is positively charged and the other is negatively charged. The charged particles are called ions or radicals. The positively charged ions are called cation or basic radical. The negatively charged ion is called anion or acid radical. In the qualitative analysis of an inorganic

An Introduction to Qualitative Analysis Purpose: Tests the ions of Mg2+‚ Ca2+‚ Sr2+‚ and Ba2+‚ and identify them separately. By using these observations‚ identify the unknown ion. Then tests the ions of SO42-‚ CO32-‚ Cl-‚ and I-‚identify them separately‚ and use the observation to identify the unknown. Procedure Part I - Qualitative Analysis of Group 2 Elements Mix 0.02M K2CrO4 with each Mg(NO3)2‚ Ca(NO3)2‚ Sr(NO3)2 and Ba(NO3)2 together. Secondly‚ mix 0.1M (NH4)2C2O4 instead

A person can feel overwhelmed‚ a loss of control‚ loss of autonomy‚ and feeling flawed after an episode of bipolar disorder. A qualitative study was performed to research the ways that bipolar disorder impacts a patient’s life and day to day living. Problem Statement Patients have many problems controlling their bipolar disorder. Medication can be effective in the acute stage; however

Write up for Qualitative Analysis 1. Introduction- This experiment is for qualitative analysis so we are trying to find out what is in a substance. In this case we are using the flame test to try and discover what is in 4 unknown sample solutions that we have been given this is done by cross referencing the colour of the flame with 6 known solutions we test beforehand. Aim- In this experiment we are attempting to distinguish what substances are in the 4 unknown solutions by cross referencing
