Things that i learn from lab notes:
-the parts of a burette and pipette.
-how to handle the apparatus.
-before using any apparatus, i have to rinse them with distilled water.
-after rinsing th apparatus with distilled water, i have to rinse them with the original solution.
-i cannot rinse the conical flask with the original solution because this will result in an increase in amount of titrant used.
-i have to make sure that there is no air bubble at the tip of the burette.
BROMOTHYMOL BLUE; strong acid-strong base
PHENOLPHTHALEIN; weak acid-strong base
METHYL ORANGE; strong acid-weak base
Hi Ashvin,
ReplyDeleteCan you still recall the titration curve that Ms Jee mentioned during lab last week? So the choice of indicator depends on whether its working range coincides with the region of sharp increase in pH (the vertical line) :D
