Question

1 mole of nacl has lesser elevation in boiling point than 0.1 mole of bacl2 dissolved in one litre of water .why

Answer 1

because the boiling point of water is 100* cellius so bacl2 is add in 1 ltr water so boiling point of water +boiling point of bacl2 is higher than nacl

Answer 2

Answer:

Elevation in boiling point temperature ( ∆Tb)

is a collgative property. Tt dep[ends upon the number of particles (of ions) furnished by the solute in solution. Both the solutes have the same molar concentration in solution. However, 0.1 mole

Bacl2

gives more ions per molecule as compared to 0.1 mole NaCI solution. NaCI solution has lesser ∆Tbas compared to 0.1 mole bacl2 solution.
