If I have 80 grams of NaCl in 100 grams of water at 20 C, is that undersaturated, saturated or oversaturated?
Look up the solubility of NaCl at 20.0C and you will know. .
undersaturated. NaCl is about 36 grams when its temperature is 20 degrees C.
To determine whether the solution is undersaturated, saturated, or oversaturated, we need to compare the amount of solute (NaCl) present in the solution to the maximum amount of solute that can dissolve in that particular solvent (water) at a given temperature (20°C).
To find out the solubility of NaCl in water at 20°C, we can consult a solubility chart or perform a search online. According to the solubility of NaCl in water at 20°C, it is approximately 35.7 grams per 100 grams of water.
In your case, you have 80 grams of NaCl in 100 grams of water.
Since the amount of NaCl (80 grams) is more than the solubility of NaCl (35.7 grams) in the same amount of water at 20°C, the solution is considered oversaturated.
Therefore, the solution of 80 grams of NaCl in 100 grams of water at 20°C is oversaturated.
