You Welcome!!! :) Do you know what a suck-back problem is??? It was one of the answers on the chem papers that i was doing for paper 6.
nid404:
I can answer with relevance to the question...so put the paper up...let me see the setup...then i'll come to know of it
saywhatsaykobe:
Here it is. Question 6c. And also 6a.
nid404:
heat applied more towards the end of the test tube...close to the liquid alkane...
okay, if the heat is turned off first, there is a sudden drop in pressure, the water could be drawn into the tube...this is suck-back
To prevent this, the delivery tube is taken off first
saywhatsaykobe:
