What is responsible for the blue colour of the solution of alkali metal in liquid ammonia? Give chemical equation also. |
|
Answer» The solvated electron, [e(NH3)]– or ammoniated electron is responsible for blue colour of alkali metal solution in NH3. It absorbs light from visible region and radiates complementary colour, (in the equation am = ammoniated) Na+(am) + e–(am) + NH2(l) → NaNH2(am) + \(\frac{1}{2}\)H2(g) |
