Purpose: The purpose of this experiment is to: determine the limiting reactant of a chemical reaction that involves iron filings and a copper sulfate solution. Second‚ to determine the mole ratios between iron and copper and to show that a single replacement reaction occurs when iron and copper sulfate react with each other. And lastly‚ to determine/calculate the percent yield to better analyze the chemical reaction between iron and copper sulfate to produce copper and iron sulfate. The method

The color change proved it was a chemical change. #2 The reaction turned yellow and it separated and created a fog. The solid formed precipitation and had a color change during the reaction proving it to be a chemical change. #3 There was green smoke and the crystals turned black. The green liquid turned dark green and continued to sizzle with

and also occurs in trace amounts in nature. It is soluble in water and is commonly used as an industrial solvent. With natural and synthetic resins‚ MEK produces solutions with low viscosity and high solids content. Properties The physical and chemical properties of MEK are determined largely by its carbonyl group. MEK engages in reactions typical of saturated aliphatic ketones. These include condensations with amines‚ aldehydes and many other organic compounds‚ hydrolysis (catalysed with acid
