Operations:-1. Check the distilled water level in the steam generator(11)2. Start the cooling water circulation in the condenser(3)3. Dilute the digested with distilled water (10-20 ml) and load itinto the inner glass tube (8) through the dropping funnel.4. Take 25 ml of boric acid solution with indicator in 250 mlconical flask and place it at the receiver end (7)5. Take 40 ml of 40% alkali and keep it ready in the droppingfunnel (1) with stop cock closed6. Now start the steam generator by switching on the heater7. The steam generator will now generates steam which passesthrough the outer jacket tube (9) and the bubble into theinner tube (8) which holds the sample8. When the steam bubbles vigorously with the digested sampleadd 40 ml of alkali immediately and close the stop cock.9. Now the digested sample in the inner tube (8) turns darkbrown10. Continue the steam distillation until liquid ammonia collectsin the boric acid solution. There will be a color change basedon the indicator used. Usually it will be red to green. Collect100-120 ml distillate in the conical flask.11. Switch off the heater and then remove the conical flask andtitrate the solution using burette.12. Now stop the cooling water circulation in the condenser13. Once the heater switched off the digested sample automatically gets siphoned into the outer jacket (9)through the siphoning tube14. Add distilled water once or twice to rinse and remove the spent reagent which might be present in theinner tube15. The spent reagent which gets collected in the outer jacket tube(9) can later be removed by open the pinch–cock and the next experiment can be started. Normally it takes 5 to 7 minutes for distillation of one sample
