Hey guys,
Not sure if this is the right place for this but thought I'd give it a go.
Here was my hypothesis: that I would not be able to get any electrical energy from a 1 uCi source of 241Am (found in my smoke detector) using Sodium Hydroxide as an electrolyte (only allowed myself to use household products for this first experiment) because of its concentration and being a pure alpha emitter
1st = 1st experiment
2nd = 2nd experiment
Here is what I found:
Glass
1st: 312 grams
2nd: same
Sodium Hydroxide
1st: 1 gram (1.25 ml)
2nd: 9 grams (6 scoops X 1.25 ml = 7.5 ml? cannot be right - scale must be off)
Water
1st: 74 grams (100 ml? Cannot be right)
2nd: Same
Glass w/ water
1st: 312 + 74 grams = 386 grams
2nd: same
Americium-241
1st: 1 micro curie
- No electrical effect
2nd: same as 1st
- no electrical effect
9 volt battery
1st: Very little electrical effect - small chemical reaction probably due to concentration of Na OH
2nd: similar to 1st
- presence of sodium bicarbonate in ball form could interfere w/ electrical effect (that's why using drain cleaner is not such a good idea; but 1 mCi of an Alpha source may not be enough - need something stronger)
2nd observation: Liquid mixture turns blue from the drain cleaner additives hard to tell what is the sodium hydroxide from the other chemicals, especially the particulates
Try to remove particulates as much as possible this had no affect on the electrical effect
Larger concentration does create a more poignant odor there may be some ammonium in the solution
Experiment absolute failure to produce intended result; confirmed hypothesis that a 1uCi alpha emitting source is ineffective for electrical energy in presence of electrolyte (either need higher concentration or something stronger)
Sodium hydroxide is a good electrolyte while widely available it has disadvantages at least in terms of smell (making it hazardous to use at higher concentrations), cleanliness (left slight discoloration on copper leads and in glass jar, may have even eroded the conv. positive lead in both experiments) unless some of this can be explained based on the other chemicals present in the drain cleaner I used (Zep Commercial contains these ingredients: Sodium Hydroxide, caustic soda, soda lye sodium nitrate, chile saltpeter, soda niter aluminum, metallic granules sodium carbonate, soda ash, carbonic acid)
Let me know ways to get better results
