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

Qualitative research methodologies comes from the understanding of f disciplines‚ including anthropology‚ sociology‚ psychology‚ linguistics‚ communication‚ economics‚ and semiotics. Historically‚ qualitative methodologies have been available much longer—some as early as the 19th century than the quantitative tools marketers rely on so heavily. (2014) Donald R. Cooper Quantitative research attempts precise measurement of something. In business research‚ quantitative methodologies usually measure

Introduction: The purpose of this lab will be to investigate the concepts of accuracy and precision for quantitative measurements using density as an example. The density of a sample will be found experimentally and compared to a known value. The relationship of averages and different analysis techniques to percent error will also be explored. Density is a characteristic of a substance which can qualitatively be described as the amount of matter (mass) squeezed into a given space (volume). The

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

DISCUSSION: Qualitative analysis is used to determine the presence of cations or anions present within a sample and their impurities. Information known‚ such as chemical and physical properties‚ about cations and anions can be used to determine what steps should be used to separate the sample into one‚ specific ion. Qualitative analysis involves forming and decomposing complex ions. Qualitative tests are very sensitive‚ allowing to detect a very small amount present in sample. Due to sensitivity

Fiscal stimulus through Quantitative easing In the event of escalating financial crisis‚ the Federal Reserve was faced with difficult choices despite previously terming the problem as isolated to certain markets. Quantitative easing was one of the choices that it had to make in order to salvage the economy. This is a monetary policy that involves purchasing of large quantities of long term assets while maintaining a large portfolio of government debt. The intended effect is reducing the long-term

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

Introduction: Data analysis is an attempt by the researcher to summarize collected data either quantitative or qualitative. Generally‚ quantitative analysis is simply a way of measuring things but more specifically it can be considered as a systematic approach to investigations. In this approach numerical data is collected or the researcher transforms collected or observed data into numerical data. It is ideal for finding out when and where‚ who and what and any relationships and patterns between
