if the salt saturated aqueous solution is heated at 60degree C what will happen and why?

Answer 1

Yes...it will get hotter...now if you actually meant a solution of salt that had excess salt that is undissolved because the system reached equilibrium before it could dissolve, you would dissolve the excess salt by raising the temperature, creating a supersaturated solution. This occurs because by increasing temperature, you are increasing the Ksp value, allowing more salt to go into solution.

EDIT:
The person below has a point, but it doesn't matter with this particular case since water normally boils at 100 degrees C...raising the temp to only 60 will not allow any observable change in solution properties.

Answer 2

it just depends upon the type of solvent you use for the solution. Boiling point [B.P] is a property based upon the solute particles also so due to the fact of b.p elevation if a solute is mixed with a solvent, the b.p of the solvent/solution will rise.

Answer 3

It will get hotter. What did you expect?
