Stability
editThere appear to be some errors in the "Alkali metal - ammonia solutions" section. Some descriptions regarding density of solutions and concentration seem backwards. 134.76.63.1 (talk) 15:06, 10 January 2011 (UTC)
Uh oh, so metals in ammonia still react after a while? -lysdexia 14:58, 12 October 2007 (UTC) —Preceding unsigned comment added by 68.123.4.253 (talk)
- Yes, they eventually react, if not with the ammonia, then with the walls of the container (usually glass). The rate of decomposition can be as low as 1% per day. The reaction is promoted by light. Any traces of transition metals, notably iron, will catalyze the reaction:
- NH3 + Na+ + e- ---->1/2 H2 + NaNH2

editCould anyone get a photo of a solution containing solvated electrons to illustrate the blue color of the solution (perhaps Na in NH3)?---- Bfesser (talk) 18:33, 16 November 2007 (UTC)

INCOMPLETE, ERRORS
editOne item which is in error is the mention of the blue color independent of what metal cation is used. Different metals give different colors if the ammonia solution is kept in quartz rather tha Pyrex. In Pyrex it is the sodium from the sodium silicate which leads to cation exchange and the common blue color.
The important work of James Dye is totally overlooked.
Anotehr Error
editThere is mention of only an Electride being in solution. Actually there are three - the Electride, the Alkide and the Free Electron.
Thus, there is a lot of literature to be read.
But the article, nevertheless, should be rated as very important.
Links to sources
editSome sources regarding the solvated electron are pointed out in the next link: [1]--82.137.9.119 (talk) 05:02, 27 June 2013 (UTC)

Presence in equations
editAlthough the solvated electron has been described, it seems that this description is limited to a rather qualitative approach. Are there some sources regarding the involvement of the solvated electron concentration in formulas like Nernst equation?--188.26.22.131 (talk) 09:00, 2 August 2013 (UTC)
