Do a fountain experiment with a flask full of ammonia when water fills the entire flask When the flask is filled with water and not filled with water, which ammonia substance is in high concentration and why
It's the same size. It's done in the same proportion. It sucks in as much water as it consumes so it's the same concentration.
The dry ammonia gas is collected by exhaust air method in a dry flask with a volume of 1 L. After collection, the relative density of the gas to hydrogen in the flask is 10. What is the volume of the solution entering the flask after the flask is subjected to a fountain test?
A cross method
The average molar mass of air was 29 g/mol
Air:29 10-2=8
\ /
10
/ \
Ammonia:2 29-10=19
Therefore air: ammonia=8:19
So the volume into the flask is (19/27) L
