How would I go about doing this??

Question

You are given 5 labeled test tubes containing gases. Your partner inadvertently spilled water over the labels causing the ink to run and smudge. The teacher demanded that you both determine, with out her help, the identity of each of the gases. Plan and design an experiment to determine the identity of each of the gases.
Clues:
a) The white gas in test tube 1 is an acidic gas with a choking smell.
b) Test tube two contains a neutral gas used to preserve snacks.
c) Test tube 3 contains a soluble alkaline gas
d) Test tube 4 also contains an acidic gas, but one that is weakly acidic.

e) The purple gas in test tube 5 has a pungent but characteristic smell.

Thanks for your answers so far guys, I'm sure they will help me out significantly. But can you also suggests some test or ways of testing these instead of telling me the names of the substances??

1.)hydrochloric acid
read the properties of acids bases and neutrals to do this

Answer 3

first single out possibilities by
color
then
acidic/basic
then
smell
make a flowchart thingy
EXAMPLE
