THE VOLUMETRIC DETERMINATION OF A GIVEN ACETIC ACID SOLUTION REQUIRED BY USING 100 ML. OF A STANDARD CAUSTIC SODA SOLUTION.
Compound
Microscope
1. Procedure for storage of apparatus and chemicals needed for the experiment: Enquire from the lab technician how the various apparatus' and chemicals listed below are used for experiment and how they are stored.
2. Prior preparation for titration: Enquire from the lab technician about the reagents or solutions he himself prepares and about those which are prepared by students. Also what method the technician uses to prepare the solutions and what amount per student does be prepare.
3. Method of Calculation for amount of solution to be prepared : Find out from the lab technician how he calculates the amount of the solution he has to prepare for all the students so that the solution prepared by the lab technician is neither too much nor too little. Is the amount of solution prepared on the basis of the requirements of each student or is some other calculation made? Also enquire if the solutions are prepared a day or two before the experiments or on the same day. After the experiment do the technicians retain the unused solution or do they discard them. If the chemicals are not discarded, how long can they be kept?
4. Glasswares used and their method of cleaning it: Enquire and list any five types of glassware which the technicians keep for preparing various solutions and also list any five types of glassware needed by the students for the experiment. How are these glassware cleaned both before and after the experiment?
5. Wind-up and disposal procedure after the experiment and at the end of the day: Find out from the lab technician what cleaning procedure he follows after the 3 experiment and at the end of the day.
6. General cleaning and maintenance of equipment procedure: Enquire from the lab technician how some of the important apparatus used in the chemistry lab experiment are maintained and cleaned.
