Which of the following processes are spontaneous? i. dissolving more solute in an unsaturated solution ii. dissolving more solute in a saturated solution iii. dissolving more solute in a suspersaturated solution

I. dissolving more solute in an unsaturated solution

Explanation:

A saturated solution is the solution which contains maximum concentration of solute dissolved in solvent.

However, if the solution is being provided with energy (heating) , it will dissolve more heat and the solution that cannot even dissolve more solute after heating is super saturated solution.

Both saturated and supersaturated solutions have maximum of their capacity to dissolve the solute and hence further energy requires energy and these processes are non-spontaneous.

An unsaturated solution can dissolve more solute easily and thus is a spontaneous process.

i think   the answer is c hope i'm right

so what is the problem with your lab report and whats the subject of the lab report? i will you
