THE GRAVIMETRIC DETERMINATION OF SULFATE Learning Goals. 1. To determine the amount of Sulfate in an Unknown sulphate sample. 2. To perform and develop skills in precipitation Gravimetric method of quantitative analysis. DISCUSSION: Gravimetric analysis is one of the oldest analytical techniques and for this reason is referred to as a "classical method." Gravimetric procedures are usually very accurate‚ but more tedious than other methods. The only major equipment needed

Midland Chemical Assignment Midland Chemical Co. is negotiating a loan from Manhattan Bank and Trust. The small chemical company needs to borrow $500‚000. The bank offers a rate of 8 ¼ percent with a 20 percent compensating balance requirement‚ or as an alternative‚ 9 ¾ percent with additional fees of $5‚500 to cover services the bank is providing. In either case the rate on the loan is floating (changes as the prime interest rate changes). The loan would be for one year. a. Which loan carries

GRAVIMETRIC DETERMINATION OF SULFATE Purpose You will be given a solid powder‚ which has been dried to constant mass. The sample is water soluble. The purpose of this experiment is to determine the concentration of sulfate in your solid sample using gravimetric analysis. Background Gravimetric Analysis The goal of most quantitative chemical analysis measurements is to estimate the relative abundance of an analyte in a chemical sample. For solid and liquid samples‚ a very common expression

Chemical Engineer The chemical engineer is an invaluable link between scientific principles and manufacturing realities. It involves the use of chemical‚ physical‚ and engineering principles. The scientist in a laboratory does basic research to develop new compounds and processes. When the scientist discovers a product that may be useful‚ the chemical engineer takes over. They adapt the product for big scale manufacturing. They do this by designing a plant to produce the item on large scale

Chemical Weapons Chemical weapons use the toxic properties of chemical substances rather than their explosive properties to produce physical or physiological effects on an enemy. Although instances of what might be styled as chemical weapons date to antiquity‚ much of the lore of chemical weapons as viewed today has its origins in World War I. During that conflict "gas" (actually an aerosol or vapor) was used effectively on numerous occasions by both sides to alter the outcome of battles. A significant

2 Chemical warfare What is Chemical Warfare: To understand chemical warfare you must first understand what a chemical agent is. A United Nations report from 1969 defines chemical warfare agents as " ... chemical substances‚ whether gaseous‚ liquid or solid‚ which might be employed because of their direct toxic effects on man‚ animals and plants ... ". This means basically that any chemical that is used to directly effect and harm a person‚ plant‚ or animal would be an act of chemical warfare

Chemical Reactions Chemical Reactions Introduction In this paper you learn about the reactions that occur between backing soda and lemon juice. We will also describe what is occurring with the molecules on a molecular level. Lastly we will explain what chemical bonds are formed and or broken when lemon juice and backing soda. Observations of the Reactants When most people hear baking soda they think of the bright orange box sitting in their pantry or refrigerator soaking up the foul odors

Chemical Engineering Chemical Engineering is the branch of engineering concerned with the design and operation of industrial chemical plants. I have been interested in chemical engineering at a young age because I have plenty of engineers in my family. I was influenced by my family to go into engineering because I witnessed how much my family worked‚ and how much it is able to support my family. Becoming an engineer ensures me of a stable job‚ and I will be financially stable. Chemical engineering
