Now+a+days+which+type+of+burette+is+used+instead+of+rubber+tube+with+pinch+corck?​

Answer 1

Answer:

permanganate titration

Explanation:

The pinch-cork is not good for fine controlling. Moreover, in the case of titration using permanganate, the rubbery material used may react to some extent with permanganate and the results may not be accurate. The advantage with that is it is cheap and does not break as easily as the other and there is no fear of clogging of stopper.

Now a day "Burette with Teflon stopcock" is used instead of rubber tube with pinch corck.
