I'm conducting a cloud chamber experiment using: Jar (black lid) Felt(black) Methylated Spirits (96% ethanol) Water Cobalt 60 Dry Ice Concentration about 50-50 with the spirits and water then soaked the felt. Using a projector which produces heat to main a temperature gradient. So far in the 2 runs I've done it has been unsuccessful in producing a cloud, however it is visible that there is rain and the diluted alcohol is being evapourated. One run was straight spirits solution and one was diluted. When I took the lid off the jar after, which was immediately after ceasing the experiment, mist bellowed out and the jar lid had like a liquidy/water feel it to. I'm going to try it again tomorrow in the hope of success and with Americium as it's a alpha emitter so ionisation should be far more effective. If, from my brief description of how I'm conducting this experiment, you find something errornous tell me. However my question is I'm curious as to the reactions that would be occuring with the free electron(s) floating around? With the naturally occuring equilibrium of H20 -> H+ + OH-, would the electron be attracted to the H+ ions causing H++? Also what would the ionisation be doing to the alcohol?
