While doing titrations, we are instructed to use pipette and they demonstrated how to use a pipette. But still after all this, we face difficulties of how to take precise reading from pipette. Example-
- Due to the concave water meniscus, until where to take the reading ?
- Is it really important to take every single drop of solution from pipette ? as while putting solution in beaker we see little bit drop left inside pipette.
- And what's the best way to hold pipette to avoid breaking it and easy to see the reading which we are taking ?
