Ammonia solution turns blue when alkali and alkaline Earth metals are dissolved in it. Why is the blue colour common to all? Is it because of the dissolution of electrons that is common in all cases?
Yes,that's the question.Borek said:Yes - they all behave similarly.

Do you mean liquid ammonia, or a solution of alcali metals in ammonia, not "ammonia solutions".aim1732 said:Ammonia solution turns blue when alkali and alkaline Earth metals are dissolved in it.

jwiens said:Here's a a question to which I've been wondering the answer: why do electrons solvated in ammonia not react, whereas electrons solvated in water, even under basic conditions, DO react to form H2?
chemisttree said:Electrons solvated in ammonia DO react to produce hydrogen. It forms sodium amide. It does it slowly if the ammonia is extremely cold, however.
What does it mean? Electrons (solvated) reacting with each other? In case, electrons react with the solvent.jwiens said:... why don't the solvated electrons react with each other to form H2, as in water (this was actually the question I was asking)?
jwiens said:Are you saying that the reaction is reasonably fast under ambient conditions? If that were the case, then the blue color would start to disappear, right? I haven't dealt with the stuff.
Barring the reaction with ammonia itself, why don't the solvated electrons react with each other to form H2, as in water (this was actually the question I was asking)? Is solvent reorganization too energetically costly (during reaction) in ammonia? I wonder if I can't find the solvation enthalpy for electrons in ammonia. . .
What kind of shelf life are we talking? Minutes?
bettlejuice said:I have a quick question someone, anyone...Is it possible for one to use ammonia gas, instead of liquid (i know about condensing the gas into dry ice container below temp -33 but the stuff smells awful! i live and share an apartment complex :( )? Let's say one was to put the ammonia gas into some kind of liquid absorbent it is soluble with and adding in the lithium to the solvent?
A solvated electron in ammonia solution refers to an electron that is surrounded by ammonia molecules. In this state, the electron is highly reactive and can participate in various chemical reactions.
Solvated electrons in ammonia solution are formed through the process of solvation, where an electron is captured by an ammonia molecule and becomes stabilized by the surrounding ammonia molecules.
Solvated electrons in ammonia solution have a negative charge and are highly reactive. They also have a tendency to cluster together, forming larger aggregates with more stable electron configurations.
Solvated electrons in ammonia solution have various applications in chemical reactions, such as reduction reactions, polymerization, and organic synthesis. They are also used in the production of semiconductor materials and in radiation chemistry.
Yes, solvated electrons can be produced in other solvents besides ammonia, such as water, alcohols, and amines. However, the concentration and stability of the solvated electrons may vary depending on the solvent used.
