Determination of Manganese in Steel Submitted by: ------------------- Date of Submission: 27.03.11 Objectives: In steel production aside the iron‚ which is the primary source‚ some amounts of manganese is used together with carbon. The objective of this experiment is determining the manganese amount in the steel compound by using UNICAM UV-VIS Spectrometer. Theory: Many molecules absorb ultraviolet or visible light. The absorbance of a solution increases

splint is inserted into the test tube‚ the flame will have enough fuel to fully reignite the splint. When the manganese dioxide is added‚ this will increase the rate of the production of oxygen in the reaction‚ without affecting the state of the manganese oxide. Materials: Test tube Retort stand Bunsen burner Scoopula Flint sparker 2cm of potassium chlorate (on scoopula) A pinch of manganese dioxide Procedure: The 2 centimetres of potassium chlorate was inserted into a test tube‚ which was then placed

the concentration of hydrogen peroxide. The catalyst to speed up the reaction without affecting the result will be manganese oxide. Prediction: I predict that the higher the concentration of hydrogen peroxide‚ the faster hydrogen peroxide and manganese oxide decomposes. Therefore the lower the concentration of hydrogen peroxide‚ the lower the rate that hydrogen peroxide and manganese oxide decompose. The prediction we have just made has been based on the collision theory-’Chemical reactions occur

Abstract The experiment was conducted‚ which metals manganese (Mn3+)‚ Cobalt (Co3+) and Copper Cu3+ was prepared and acac complexes where also obtained. Recrystallization was performed of which Mn(acac)3 ‚Co(acac)3 and Cu(acac)3 was obtained at percentage yield of 32%‚ 85.6% & 92% for each of acac’s. TLC was performed which results deduced unknown mixture both contained manganese and cobalt since it had the same Rf vaues. Experiment aims The aim of the experiment was to prepare metal

Experiment 2: The Effect of Different Reactants on the Type of Gases Produced Abdul Aziz Malik Submission Date: 18th April 2012 Background Information In the experiment‚ when oxygen is being tested‚ a glowing splint will be used and when that splint is placed in to the mystery gas and the splint reignites‚ then the gas is oxygen. When hydrogen is being tested‚ a burning splint will be used and when the splint is placed in to the mystery gas and a “pop” sound occurs‚ then the gas is hydrogen
