A complex iron and cyanide ions is 100% ionised at 1 m (molal) . If its elevation in b.p is 2.08 . Then the complex is (K_(b)=0.52^(@) mol^(-1) kg) :

A complex of iron and cyanide ions is 100% ionised at 1m (molal). If its elevation in b.p.is 2.08^@C . Then the complex is (K_b=0.52 K mol^-1 kg) :

A complex of iron and cynanide ions is 100% ionised at 1m (molal) . If its elevation inb.p. is 208^(@), (K_(b)=0.52^(@)mol^(-1)Kg) , then the complex is :

A complex of iron and cyanide ions is 100% ionised at 1m (mol). If its elevation in b.p is 2.8^(0) , ( K_(b)=0.52^(0) "mol"^(-1)Kg ), then the complex is :

Consider following figure and answer the questions at the end of it. Figure explains elevation in boiling point when a non-volatile solute is added to a solvent. Variation of vapour pressure with temperature and showing elevation in boiling point. A complex of iron and cyanide ions is 100% ionized at 1m (molal). If elevation in boiling point is 2.08^(@)(K_(b)=0.52^(@)mol^(-1)kg) then the complex is:

Figure explains elevation in boiling point when a non-volatile solute is added to a solvent. Variation of vapour pressure with temperaure and elevation in boiling point is marked. Elevation in b.p of an aqueous urea solution is 0.52^(@) (K_(b) = 0.52^(@) mol^(-1)kg) . Hence, mole fraction of urea in this solution is:
