OBJECTIVE The main objective of this experiment is to carry out qualitative analysis to identify metal cations in unknown solution 1. INTRODUCTION An unknown material can be determined by using simple chemical tests and separations which is called as inorganic qualitative analysis. The separation of cations depends on the difference in their propensity to form precipitates. Separation scheme is used to classify cation into five groups on the basis of their physical and chemical behavior opposed

Full Metal Jacket In the movie Full Metal Jacket‚ directed by Stanley Kubrick‚ the plot evolved around a training camp before the Vietnam War. In the training camp the soldiers learned about‚ teamwork‚ and acceptance. The group ostracizes one soldier and he kills their drill sergeant. The Movie focuses on the horror and pressure of going to war and connects with “the things they carry”‚ by Tim O’Brien. In Full Metal Jacket‚ many uncomfortable areas are addressed. The majority of this film develops

KINETIC STUDY OF LIQUID-PHASE ADSORPTIVE REMOVAL OF HEAVY METAL IONS BY ALMOND TREE (TERMINALIA CATAPPA L.) LEAVES WASTE ABSTRACT. The kinetic sorption of five metal ions - Al3+‚ Cr6*‚ Zn2+‚ Ag+ and Mn2+ - from aqueous solution onto almond tree leaves (ATL) waste in single component system has been studied. The experimental data was analyzed in terms of intraparticle diffusion and rate of adsorption‚ thus comparing transport mechanism and chemical sorption processes. The sorption rates based on

Standardization of hydrochloric acid by sodium carbonate Concentrated hydrochloric acid is roughly 11 M. Pour out into a measuring cylinder about 2 cm3 of concentrated hydrochloric acid. Transfer it to a 250 cm3 flask and make up to the mark with water. Shake well. Put some pure sodium hydrogen carbonate or anhydrous sodium carbonate into an evaporating dish and heat gently over a low flame for about fifteen minutes‚ stirring continuously. Take care not to heat the mass too strongly or fusion

and weighed. The percentage of chloride present was found to be 24.73695223 (±0.00000006) %. Introduction The purpose of this lab was to determine the percentage of chloride in an unknown soluble salt sample through a gravimetric method known as precipitation gravimetry. The objective was to accurately and precisely convert the unknown sample containing the chloride analyte to another known solid‚ silver chloride. Once the mass of the known solid is measured‚ the percentage

Executive Summary 1. We see the company considering the penetration to the new market with a new product. After testing‚ their prototype cushion pads‚ consisting of curled metal‚ performed superiorly to asbestos pads‚ which are currently the industry standard compliment product to pile drivers. 2. Despite the fact that there’s no such a product on the market at the moment. The copmany is likely to face competition from the asbestos pads market (a substitute product) 3. The potential market

Experiments with Metals and Ions of Metals Introduction Metals are similar in their physical properties in general‚ but they are not identical. Most of the metals are solids; few of them are liquids‚ such as mercury and cesium. Density of metals is not similar also. For example‚ sodium has density of 0.97g/cm3 while lead has density of 11.4g/cm3. Melting point of sodium is 98.0oC while for lead it is 327.6oC. Metals have the capability to lose electrons when they react with non-metals such as

Background: Cumberland Metal Industries (CMI) was one of the largest manufacturers of curled metal products in the country.Their sales grew from $250‚000 in 1963 to over 18‚500‚000 by 1979.It originally custom fabricated components for chemical process filtration and other highly technical applications. The company’s philosophy soon evolved from selling the metal as a finished product to selling products that used it as a raw material . Earlier CMI used to sell exaust gas recirculation(EGR) valves

Gold is a soft metal that is largely unreactive. Gold jewellery can lie underground for thousands of years and emerge shiny after that lengthy exposure to air‚ water‚ and other chemicals in the environment. Gold does dissolve in some solvents as indicated below and does react with halogens. The most common oxidation states of gold are Au(I) and Au(III) but there are a few examples of Au(V) (various anions [AuF6]- and [Au2F10]). The Au(III) ion has the d8configuration which gives rise to many square
