A) at the centre of tube
B) near the hydrogen chloride bottle
C) near the ammonia bottle
D) throughout the length of the tube
Correct Answer: B
Solution :
Molecular mass of \[N{{H}_{3}}=17\] Moleclar mass of \[HCl=35.5\] \[\because \]rate of diffusion \[\propto \sqrt{\frac{1}{M}}\] \[\therefore \]\[N{{H}_{3}}\]will diffuse faster than\[HCl\]and hence ring will be formed first nearer to\[HCl\]bottle.You need to login to perform this action.
