Mass Equilibrium Reactions
Solubility is defined as the maximum amount of solute that can be dissolved in a solvent at a particular temperature.
Now, the solubility of chromium nitrate in water is given as 208 g per 100 grams at 25 °C.
Now, when heated, the solubility of the solution will increase while when cooled, the solubility will decrease and as a result the solute precipitates out.
When the solution is slowly cooled down to 15°C , the solubility of the solution decreases, thus the solution has been a supersaturated solution.
The mass of crystal that will be expected at equilibrium will be the mass that remained undissolved.
Dissolved mass = 208 grams
Total mass = 310 grams
Undissolved mass = 310 - 208 = 102 grams.
