Experiment-6
FE 211 09.11.2004 EXPERIMENT 6 LAB REPORT Submitted By : Mutlu DEMİREL Group: 3 MATERIALS: Ca containing sample , beaker , pipette , buret , bunsen burner , florence flask , HCI , , Methyl Orange , funnel , thermometer , , PURPOSE: Determination of Calcium in a sample. METHOD: Volumetric method. THEORY: Calcium dissolves out of almost all rocks and is, consequently, detected in many waters. Waters associated with granite or siliceous sand will usually contain less than 10 mg of calcium per litre. Many waters from limestone areas may contain 30-100 mg…

FE 211 01.11.2004 EXPERIMENT 5 LAB REPORT Submitted By : Mutlu DEMİREL Group: 3 MATERIALS: HCl , , , , , , Zimmermann-Reinhardt reagent , Distilled water , Buret , Erlenmayer Flask , Graduated Cylinder , Pipet , Bunsen Burner. PURPOSE: Our purpose is to determine the iron by permanganete titration. METHOD: Gravimetric Analysis THEORY: Iron is an abundant element in the earth’s crust, but exists generally in minor concentrations in natural water systems. The form and solubility of iron in natural waters are strongly dependent upon the pH and the oxidation- reduction potential…

FE 211 25.10.2004 EXPERIMENT 4 LAB REPORT Submitted By : Mutlu DEMİREL Group: 3 MATERIALS: HCl , HAc , Phenolphthalein , Methyl Orange , NaOh , Dilute Water ,Buret , Erlenmayer Flask , PURPOSE: In this experiment we titrated HCI and HAc mixture with NaOH to determine amounth of HCI , HAc and NaOH and the molarity of NaOH. METHOD: Gravimetric Analysis THEORY: The capacity of water to accept protons is called alkalinity. Alkalinity is important in water treatment and in the chemistry and biology of natural waters. Alkalinity serves as a…

Experiment-3
FE 211 25.10.2004 EXPERIMENT 3 LAB REPORT Submitted By : Mutlu DEMİREL Group: 3 MATERIALS: 0.1 M NaOH , Potassium Hydrogen Phthalate , Desiccator , Phenolphthalein , 5 ml Vineger , Distilled water , Flask , Buret , Erlenmayer Flask PURPOSE: In this experiment our aim is to determine the molarity of NaOH and weight percentage of with neutralization titration. METHOD: Gravimetric Analysis THEORY: Both NaOH and HCl are frequently used reagents: the former an example of a strong base, and the latter an example of a strong acid. This classification comes from the…

Experiment-1 ( Gravimetric Analysis )
Gravimetric analysis : As the name suggests, gravimetric analysis involves very accurate weighing of a chemical as a means of working out something about that chemical. A common type of gravimetric analysis involves precipitation of a single component (usually an ion) from a known amount of a compound or mixture. This is accomplished by reacting a solution of the test compound with a solution containing an ion that forms an insoluble salt with the component you wish to test for. ….. In this experiment the sample containing an alkali sulfate…
