Both will have same vapour pressure as salt{NACL} would get trapped in ice and in solid iced state get seprated from pure ice crystals.
so in case melting of ice in soln state pure water will have more vapour pressure but in solid state both will have same vapour pressure.

What is Reid Vapor Pressure?
Under the ASTM Method D 323 (Reid vapour pressure), it is the absolute vapour pressure exerted by a liquid at 100°F. The higher this value, the more volatile the sample and the more readily it will evaporate. Unlike distillation data, vapour pressure provides a single value that reflects the combined effect of the individual vapour pressure of the different petroleum fractions in accordance with their mole ratios. It is thus possible for two wholly different products to exhibit the same vapour pressure at the same temperature - provided the cumulative pressures exerted by the fractions are the same. A narrow-cut distillate, for example, may exhibit the same vapour pressure as that of a dumbbell blend, where the effect of heavy fractions is counterbalanced by that of the lighter ones. In conjunction with other volatility data. Reid vapour pressure plays a role in the prediction of gasoline performance.
Why do you cool down more slowly on a humid day than when air is dry?
The answer to this is related to partial pressure of water. When humidity is high this means that there is a lot of water suspended in the atmosphere. This means that water in liquid form will not tend toward evaporation into it's gas phase but will stay as liquid.

What is the difference between water vapour and steam?
the difference is that water vapour is just one particle that joins together with more and more to form steam
Which has more energy vapor or solid?
vapour
Does salt water boil fast as fresh water?
Salt water boils at a higher temperature than fresh water. If a substance (salt) has a lower vapour pressure than the liquid (water) (it's relatively non-volatile in other words) then dissolving that substance in the liquid, common salt (NaCl) in water (H2O), for instance, will lower the overall vapour pressure of the resulting solution compared with the pure liquid. A lower vapour pressure means that the solution has to be heated more than the pure liquid to make its molecules vaporise. It is an effect of the dilution of the solvent in the presence of a solute.
Does the evaporation in the evaporation column influence the total pressure?
evaporation as such influence on the total pressure. evaporation occurs when the total pressure is greater than the surface molecules vapour pressure. as the rate of evaporation increases , more vapour will be there at the top, and then the new total pressure will become the sum of the earlier total pressure and vapour pressure of the vapour evaporated. hence total pressure increases.............
What is difference between cavitation and supercavitation?
CAVITATION is the process of formation of vapour bubbles of flowing fluid in a region where the pressure of the liquid falls below its vapour pressure and the sudden collapsing of these vapour bubbles in region of high pressure. where SUPERCAVITATION IS THE CONTROLLED FORM OF CAVITATION WHICH HELP US TO attain more underwater speed
Why is the bore of the capillary tube of a mercury thermometer made narrow?
Answer Vapour Pressure and Precisiondh25sThe vapour pressure of mercury (Hg) is low (0.0017 torr at 25 oC). The vapour pressure is dependent on temperature, thus what you want to measure. As the temperature increases, the vapour pressure increases and the mercury imbibes further up the capillary. If the capiallry radius were larger, the readings would be more difficult to see, i.e. the precision would decrease. Vapor pressure has nothing to do with how a Mercury thermometer works. As the temperature rises, the mercury expands into a narrow bore, because the volume of the mercury increases. If the bore is very narrow then the extra volume has to go a longer way up the bore to accomodate that volume, so it is more sensitive to small changes of temperature.

Do you breathe in or breathe out more water vapour?
You breathe out more water vapour then when you breathe in
How does temperature effect vapour pressure of a liquid?
as the temperature increase the liquid becomes less condensed and the pressure decreases. as its molecule lossen they move faster, the liquid will turn into a gas. if the temperature decreases then it will do the opposite. it would slow down the molecules, and increase the pressure, making a solid.
What is the pressure in domestic LPG cylinder?
Pressure in an LPG cylinder is dependant of the ambient temperature and the LPG mix considered. For 70% Propane and 30% Butane at 20 degrees Celsius the pressure is 102 PSI (lb/sq.in.) or 703 KPa. Please be aware that the pressure inside an LPG vessel will not drop as vapour LPG is being used. LPG cylinder is not to be understood and dealt with as a pressurised gas storage cylinder that will drop in pressure if gas is being taken out of the cylinder. LPG cylinder contains both liquid and vapour, as vapour is being used at an appliance the liquid vaporises under natural conditions and generates more vapour, hence the efficiency of the LPG storage systems.
Why evapourate at a low pressure?
Reducing the air pressure allows the molecules to escape
Why humans exhale more water vapour than they inspire?
Humans exhale more water vapour than they inhale because water vapour is a product of respiration which means that your body creates it so has more to get rid of.
What would you describe actone in the gaseous state as vapor or a gas?
Vapour. Generally, 'gas' describes the state of a single element, whereas 'vapour' is used more commonly with compounds like acetone.
Which of the following factors affect the vapour pressure of a liquid?
Type of molecule: intermolecular forces between molecules are: * relatively strong, the vapor pressure will be relatively low. * relatively weak, the vapor pressure will be relatively high. Temperature: * higher temperature, more molecules have enough energy to escape from the liquid or solid. * lower temperature, fewer molecules have sufficient energy to escape from the liquid or solid.
