Question

Does table salt(NaCl) increase or decrease the boiling point of water(H2O) ?state the reason

Answer 1

The salt actually increase the boiling point of water.

Salt increases water's boiling point, or the temperature it must reach in order to boil. This new salt water solution needs more heat to start boiling than pure water does, so the time it takes to boil increases slightly. So your water is hotter, but it's not boiling any faster.

Hope it helps !

Answer 2

the boilng point will increase.Because NaCl (solute) will bind the solvent molecule more tightly.The vapour pressure of solvent will decrease.It will take more time to boil because the boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.
