Procedure: 1. Iron (III) and copper (II) sulfate solution Fill a small test tube halfway with copper (II) sulfate solution. Add a 2.0 gram iron rod to the solution and observe the reaction. The Iron shavings change from dark gray to brown when it mixes with copper that changes from transparent to blue. 2. Lead (II) nitrate and potassium iodide solutions Pour about 2.0 mL of lead (II) nitrate into the test tube. Add 5 to 10 drops of potassium iodide solution to the test tube and record your

The presence of nitrogen was tested with ferrous ammonium sulfate and potassium fluoride. The presence of any halogen was tested by a flame test with copper wire and the identification of the exact halogen was done using silver nitrate. Careful experimentation was needed in order to avoid false positive and false

Aqueous Solutions Reactions‚ Metathesis (Double Replacement) Reactions and Net Ionic Equations Terrance Shelton Introduction India’s cultural treasure and biggest tourist attraction is slowly losing its magnificent appeal due to decades of acid rain. The walls of the Taj Muhal are composed of a marble-like substance ( CaCO3) that corrodes and eventually crumbles when reacted with acid rain(H2SO4). Not only is the Taj Muhal suffering‚ but also other historic landmarks across the world. This is

For the experiment we used 2-Methylcyclohexanol as a beginning reagent to dehydrate and possibly form 3-methylcyclohexene‚ 1-methylcyclohexene‚ or methylenecyclohexane. Drierite® (Calcium Sulfate) was used as a drying agent to help break the alcohol and hydrogen groups from the carbons. Concentrated phosphoric acid was used as a catalyst to help move the reaction towards the products motioned above. To determine the successfulness of the experiment

FACTORS AFFECTING SULFUR MINERALIZATION Sulfur content of organic matter Mineralization of sulfur depends on the sulfur content of the decomposing material in much the same way that nitrogen mineralization depends on the nitrogen content. Smaller amounts of S042- are liberated from low sulfur containing residue‚ which is similar to nitrogen mineralization. At or below a C/S ratio of approximately 200/1 only mineralization of sulfur occurs. Source of mineralizable sulfur Because of the contribution
