In a basic form sun light produces heat, heat act's as a catalyst which speed's up chemical reaction. SO in a nut shell sunlight makes the dissolving process occur more rapidly.
Stirring and increasing temperature increase the dissolving rate.
Ill answer it, yes because mud would keep it from mixing and dissolving
colour is a physical property that has no effect on the rate of dissolving
it makes it faster to dissolve
Temperature afftects the solubility...see Henrys Law and chemical kinetics
The dissolving process separated the ions, atoms, and molecules of the solute with a solvent. The rate of dissolution is governed by temperature, mixing, and surface area.
The higher the temperature, the greater the rate of dissolving.
The polarity of solute and solvent, the concentration, the temperature.
increases
Yes, in fact stirring does increase the rate of dissolving [or dissolution] of solids.
When the dissolving rate equals the rate at which molecules comes out of solution the solution is in 'equilibrium'.
