• General

  While performing an experiment, is it necessary to do significant transfer? Can I use precise transfer for the same purpose?

• level on burette

  Instead of keeping the volume 50 and not levelling it up to the mark, cant we use the pipette to make up the level to the mark just like we do in the lab?

• The end point of the titration

  The end point shown in the tutorial and as well in the vlab is not so clear and using spectrometer also I am unable to identify the colour change.  Kindly help me in getting this colour change visible and as well explain how to use spectrometer.

• conjugate acid, base

  I don't really know the times, these appear in a couple of places....In theory, the conjugate base of ethanoic acid is ethanoate and the conjugate acid of ammonia is the ammonium ion.  The sodium and chloride ions are merely partner ions in this example.
