Interesting. I also find it fascinating you don't have any lab equipment at home. I am very impressed by that alone.
I also agree with your reasoning as to likelihood of the latter occurring due to 18 electron 'rule' stability. Could you cut the samarium under the
citric acid solution to try to mitigate oxidation and see if that coaxes a reaction, or did you recently manipulate it in any manner to expose a fresh
face to the acid? |
