Apply the necessary calibration corrections to the volumes of the solutions used, and correct for temperature if necessary. From the data obtained, calculate the volume of the hydrochloric acid solution which is equivalent to the volume of sodium hydroxide solution used in this titration. Subtract this volume from the volume of hydrochloric acid.
Pipettes are usually already graduated when purchased, but they require calibration for accurate work. PROCEDURE. Clean the pipette. Draw distilled water into it by sucking at the upper end until the water is well above the graduation mark. Quickly place the forefinger over the top of the tube, thus preventing the entrance of air and holding the water in the pipette.
Many of them were still in faithful service. The day would not be spent in the observation which was their main job there, because calibration of many of the instruments remained to be done, and the observatory was behind schedule, having had a good deal of its time taken up in the sightings required by the communications lab and Project Hot Rod.
That will enable us to keep in touch with the other stations. For now, I would like Dr. Mandarawi and Dr. Azrar to establish the time when the source will be within our horizon, and set up the necessary data for the operator in charge of each shift. The rest of us will check out the circuit and establish calibration to be ready for recording this afternoon."
