When adding water to the salt initially you attempted to find the minimum amount of water the salt would dissolve in at 100 degrees c Why was it necessary that the solution used be almost sturated?

Answer 1

Because, unsaturated solution have the capacity to solve more solute in it. Using unsaturated solution can result false.

Answer 2

It was necessary for the solution to be almost saturated because this ensures that the maximum amount of salt that can be dissolved in the water at that temperature has already been dissolved. By reaching almost saturation, we can accurately determine the minimum amount of water needed for the remaining salt to dissolve, helping us understand the solubility limit of the salt at that temperature.
