The supersaturated solution begin to drop small crystals when the additional sodium thiosulfate was added because the supersaturated solution got reverted back to a saturated solution. Every solution has it;s own level of saturation, at a certain temperature a limit of the solute can be disolved in it, if you heat the solution the limit changes and more of the solute can be added in the solution. This is a supersaturated solution.When you drop an extra crystal into a supersaturated solution, all the extra crystals that aren't suppose to be in it crystalize out of the solution.
A supersaturated salt solution.
I think that varying temperature and the enviorment effects the growth of sugar crystals. The water needs to be hot enough to fullr dissolve the water and also a undistrubed area to fully reach its potentail size with out interaction.
Ice crystals don't precipitate. Precipitation of crystals happens when you create a supersaturated solution, and you do THAT by heating a solvent, adding enough solute to make a saturated solution at that temperature, filtering out the undissolved solute, and letting the solution cool. Ice crystals form.
Iodine crystal is solid Iodine. Iodine solution is when Iodine crystals are dissolved in water.
why sodium thiosulfate to be prepared in hot water only
A supersaturated solution is when there is more solute present in the solution than can be absorbed by the solvent. When it is disturbed, all of the solute that is not in solution falls out, sometimes forming crystals.
A supersaturated solution is most likely to form crystals as it cools.
Supersaturated
A supersaturated solution is obtained.
If a seed crystal was added to a supersaturated solution, the resulting solution would be a crystallized solution. The formation of solid crystals that precipitate from a solution is called crystallization.
To get a supersaturated solution you can either cool down the solution or let some of the water evaporate. To begin, make some Epsom salt crystals. These are easy to grow and you will begin to see crystals in a couple of hours. Start with one cup of warm distilled water (not boiling).

Supersaturated.
The solute will eventually fall out of a supersaturated solution
The solute will eventually fall out of a supersaturated solution
The solute can re-form as a solid.
A solution of sodium thiosulfate is produced.
