Question
![p. Graham's Law
Let's say you carried out the following, where you
1. Prepare glass tubing to about a one (1) meter long.
2. Fit corks on both end of the tube (Figure 3). To both end make a 2-cm mark.
NH4OH
HCI
Figure 3
3. Prepare two cotton balls. Immerse one cotton ball in a conc. ammonium hydroxide
solution and the other with conc. hydrochloric acid.
4. Simultaneously place the 2-soaked cotton balls on both ends of the tube. Now, put
the cork back.
5. Observe carefully the formation of a white ring of ammonium chloride. Mark on the
glass tubing the spot where the ring is formed. The distance traveled by the
ammonia gas is from the 2-cm mark to the spot of the ring and that of hydrogen
chloride gas is from the other mark on its side to the ring spot. Measure their
distances.
6. Since the rate multiplied by the time equal to the distance and the time is taken to be
constant, the distance traveled may be substituted for rate, R, in the above equation.
7. Using the data in your activity, calculate the ratio of the rate of diffusion of ammonia
gas to that of hydrogen chloride gas. Compare the result of your calculation with that
obtained from the square root of their molecular weights.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6b900b0c-fca2-41f6-98be-4cea5e82fc11%2F95268427-31cc-43fd-a332-ff546459eb4f%2Fljpp7fs_processed.png&w=3840&q=75)
