Question
Highly pure dilute solution of sodium in liquid ammonia :
Options
A.shows blue colour
B.exhibits electrical conductivity
C.produces sodium amide
D.produces hydrogen gas
Solution
Pure solution of Na + NH3(l) is blue coloured and highly conducting due formation of ammoniated cation and ammoniated electron.
Na + (x + y)NH3 → [Na(NH3)x]+ + [e(NH3)y]-
ammoniated ammoniated
cation electron
If impurities like Fe etc. are present, NaNH2 amd H2 are formed.
Na + NH3(l) → NaNH2 +
H2
Na + (x + y)NH3 → [Na(NH3)x]+ + [e(NH3)y]-
ammoniated ammoniated
cation electron
If impurities like Fe etc. are present, NaNH2 amd H2 are formed.
Na + NH3(l) → NaNH2 +
