The practice which will not help me obtain an accurate volume reading on a burette at the beginning of a titration is:
Make sure that the meniscus starts exactly at 0.00 mL.
The correct option from the choices given is option a.
The main significance of reading volume on a burette while performing a titration experiment is that it enables is to easily determining the concentration of substance in the burette and in other solution at large.
That being said, it will be very difficult to obtain a good reading result on a burette if we always assume that meniscus starts exactly at 0.00 mL.
In conclusion, it can be deduced from the explanation above that when the meniscus on a burette reading falls within the marked range on the burette, it will help us get a good reading.
