OBJECTIVES To determine the chemical oxygen demand of the given wastewater samples. 2. PROCEDURE Preparing the Sample 1. Open a reaction vial with a white cap and add the specified volume. (Ensure that appropriate personnel safety equipment is used.) LR-/MR: 2 ml water sample HR: 0.2 ml water sample 2. Prepare a blank by using deionised water (TOC-free) instead of the sample (LR/MR: 2 ml, HR: 0.2 ml). 3. Replace the cap tightly. Invert the vial gently several times to mix the contents (The vial will become hot during mixing!) and digest the vials for 120 minutes in the reactor at a temperature of 150°C. 4. Remove the vials from the reactor and allow them to cool down to 60°C or less. Mix the contents by inverting each vial several times while still warm. Then allow the vials to cool to ambient temperature before measuring. 3:Results Sample COD reading (mg/L) Leachate 216 Factory 423…02:21 4G File Details 4CH003/UM1: Fundamentals of... Place a thermometer into the mixture and cool the flask in a water bath until the temperature is below 200C. Remove the flask from the water bath and carefully add cyclohexanol (10ml, 9.6g) to the acid mixture. Cyclohexanol is only slightly soluble in water so you should observe two immiscible layers at this point. Dissolve sodium dichromate dihydrate (10.5g) in water (5ml) in a 25ml conical flask and, using a dropping pipette, add this solution carefully drop by drop to the cyclohexanol/sulphuric acid mixture over about 30-40minutes. Swirl the flask vigorously during the addition process and maintain the temperature of the mixture in the round bottomed flask between 25-35°C during the addition by immersion of the flask in the cold water bath. If the dichromate solution is not added slowly, a rapid rise in temperature will occur and the reaction will become violent. 3 When all the dichromate solution has been carefully added rinse…
- Case: A prescription for calls for compounding 60 mL of an oral solution for patient A. This oral solution contains 45 mg of salicylic acid. The pharmacist decides to weigh this on a balance with a minimum weighable quantity of 120 mg and dissolve it an appropriate solvent to prepare the solution. Answer the following questions to explain how you will use the liquid measurement aliquot method to obtain the correct amount of salicylic acid to prepare this solution. When making this preparation, you want to minimize the amount of salicylic acid that is wasted. The prescription is as follows: Rx Salicylic acid 45 mg Cherry flavor solution 5 mL Ora-Syrupee qs 60 mL What is the target amount of salicylic acid for the liquid aliquot that will be used to make the 60 mL oral solution?
