Why must you let a solution evaporate at room temperature in order to get a salt?
The solution does not have to be at room temperature. Depending on what the solution is, the solution must be heated to it's proper boiling point in order for it to evaporate. Everything has a melting, freezing and a boiling point, and the salt's melting and boiling point's are extremely high, therefore the salt will be left behind when the solution is evaporated, unless the solutions boiling point is higher then the salt's boiling point.
What lowers the freezing point and raises the boiling point?
Yes, it is possible if the solution contain solutes.
What happpens to the boiling point of a solution?
At the boiling point liquids become gases and if the solution contain dissolved solids they remain as residues.
Is alcohol solution boiling point higher or lower than salt solution?
Lower. The boiling point of ethanol is 78 degrees C. Adding salt to water raises the boiling point of that solution above 100 degrees C.
Which has a higher boiling point 0.50 NaCl or 0.50 MgCl2?
The magnesium chloride solution has a higher boiling point.
Calculate the boiling point of a solution of 10 grams of sodium chloride in 200 grams of water?
The boiling point will be approx. 100,81 0C at 760 mm col. Hg.
The boiling point of a liquid solution is?
Higher then the boiling point of the solvent.
The difference between the boiling point of a liquid in pure state and the boiling point of the liquid in solution?
Boiling Point Elevation
What is the boiling point of a solution of 72.4 grams of glycerol dissolved in 122.5 grams of water?
First find the molality--convert the 72.4 grams into mols; convert the grams of water into kilograms. Divide the mols by the Kg, which gives you 6.419m.No need to find the mol ions since it's a molecular compound.The molar boiling point constant for water is 0.51.Therefore:Tb=0.51(6.419)Tb=3.27since this is the boiling point elevation and we're trying to discover the new boiling point, add this number to 100 (the average boiling point of water)the final answer is 103.27o c

What is the boiling point of a 2.0 molal solution of glucose?
The boiling point is 101 oC.
What is the boiling point of a 2.47 molal solution of napthalene in benzenethe boiling point of benzene is 80.1?
the boiling point of platnium is 2500c
What happpens to the boiling point of a solution?
At the boiling point liquids become gases and if the solution contain dissolved solids they remain as residues.
What happens to the melting and boiling point of a substance if it contains impurity?
If the impurity has a higher boiling point then the boiling point of the mixture will also be slightly higher, and vice versa.
How does the number of dissolved ions in solution affect the boiling point of of that solution?
Dissolved ions in solution will increase the boiling point of the liquid. Salt in cooking water does this.
Is alcohol solution boiling point higher or lower than salt solution?
Lower. The boiling point of ethanol is 78 degrees C. Adding salt to water raises the boiling point of that solution above 100 degrees C.
