Question

Through the two ends of a glass tube of length 200 CM hydrogen chloride gas and ammonia are allowed to enter at what distance ammonium chloride will first appear

Answer 1

Answer:

Thus, rate of diffusion of NH3/rate of diffusion of HCl = 1.463 = R1/R2 = R1/200-R1(Since the total length of the tube is 200 cm). Therefore, R1 = 118.81 cm. Hence,at a distance of 118.81 cm from NH3 end and at a distance of 81.19 cm from the HCl end, ammonium chloride will first appear.
