A) nearer to the \[HCl\] end
B) at the centre of the tube
C) throughout the tube
D) nearer to the \[N{{H}_{3}}\] end
Correct Answer: A
Solution :
White ring of \[N{{H}_{4}}Cl\] will appear nearer to the \[HCl\] end. The rcason is that \[HCl\] (mol. wt = 36.5) is heavier than \[N{{H}_{3}}\] (mol. wt = 17). Hence, according to Grahams law of diffusion, the rate of diffusion of NHs will be higher than that of \[HCl\]. \[\frac{{{r}_{1}}}{{{r}_{2}}}=\sqrt{\frac{{{M}_{2}}}{{{M}_{1}}}}\]You need to login to perform this action.
