Scientists have finally unlocked the mysterious transition behind a century-old chemistry experiment. The mysterious transition has long puzzled the scientists and involves a glossy, metallic bronze that produces after adding electrons to a bright blue ammonia solution. Scientists were able to explore the subtle details of this change using a microjet technique and show that this transformation is gradual, rather than abrupt. For the first time, scientists have used a technique that involves shooting hair-thin streams of the solution through a vacuum on the lustrous liquid. The breakthrough seems promising and could open up new types of reactions in organic chemistry in the future.
