If for a sucrose solution elevation in boiling point is 0.1^(@)C then what will be the boiling point of NaCl solution for same molal concentration

Answer»

`0.1^(@)C`
`0.2^(@)C`
`0.08^(@)C`
`0.01^(@)C`

Solution :Elevation in a BOILING point is a colligative property as it depends upon the number of PARTICLES.
`Delta T_(B) ptop n`
For SUCROSE, `n = 1, Delta T_(b) = 0.1^(@)C`
For NACL, n = 2, `Delta T_(b)=0.2^(@)C`
