Question

At 50C, liquid NH3 has ionic product is 1030. How many amide (NH2) ions are present per mm3 is pure liquid NH3? (Take NA=6×1023).
  1. 500 ions
  2. 602.2 ions
  3. 222.2 ions
  4. 22 ions

A
602.2 ions
B
22 ions
C
500 ions
D
222.2 ions
Solution
Verified by Toppr

ionic product of NH3=KNH3=[NH+4][NH2]=1030
[NH2]=1030=1015M
Since, 1L contains 1015 moles
1mm3 will contain 1015/106 moles=1021 moles
number of NH2 ins=6.022×1023×1021=602.0 ions.
