1.	The solution having vapour pressure is (assume 100% ionisation of electrolytes)(a) IN KNO3 (b) IN Ba(NO3)2(c)1 N Al2(SO4)3 (d) IN Th(NO3)4
Answer» ong>ANSWER: Van't Hoff factor =i For BA(NO 3 ) 2 ,i=3; Ba+2NO 3 − For NACL, i=2; Na + +Cl − For Glucose, i=1 So higher the van't Hoff factor, higher is the lowering of VAPOR pressure So Ba(NO 3 ) 2 will have the highest lowering of vapor pressure. Option C is correct.

The solution having vapour pressure is (assume 100% ionisation of electrolytes)(a) IN KNO3 (b) IN Ba(NO3)2(c)1 N Al2(SO4)3 (d) IN Th(NO3)4

Answer»

Van't Hoff factor =i

For BA(NO

)

,i=3; Ba+2NO

−

For NACL, i=2; Na

+Cl

−

For Glucose, i=1

So higher the van't Hoff factor, higher is the lowering of VAPOR pressure

So Ba(NO

)

will have the highest lowering of vapor pressure.

Option C is correct.
