2) Liquid ammonia ionizes to a little extent

At -500 C , Its ionic product is KNH3 = [NH4+][NH2-] = 10-30

The no of amide ions present in 1 mm3 of pure liquid NH3 would be

A) 10-15 ions/mm3

B) 600 ions/mm3

let the conc of both be xM
then acc. to ionic product
x2 = 10-30 this gives x to be 10-15.
thus conc. of amide ions per litre ofammonia is 10-15.
