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…

Volumetric pipets are calibrated in a manner that takes into account the solution which remains at the tip. True Using the pipettor, you should turn the wheel on the pipette, draw up the solution until the meniscus is several centimeters above the calibration line, then quickly remove the pipette and put your thumb over the open hole of the pipet. True When the bottom of the meniscus coincides with the calibration mark, your pipet contains a precisely measured volume. True e Do not force the pipet into the pipettor, be gentle.
