A solution contains 32 g of KNO3 per 100g of water at 25 degree C. Is the solution unsaturated, saturated, or supersaturated?
I think its saturated
Look at your saturation chart. I will be happy to critique your thinking.
is there one online?
The right answer is "unsaturated"
who’s right?
Yes, there are many saturation charts available online. You can search for "KNO3 solubility chart" or "solubility chart" to find one that includes potassium nitrate (KNO3). Once you find a chart, locate the temperature of 25 degrees Celsius and look for the corresponding value for KNO3 solubility in water.
Most likely, the solubility value for KNO3 at 25 degrees Celsius will be provided in units of grams per 100 grams of water (g/100g). Compare this value to the concentration given in the question, which is 32 g KNO3 per 100g of water. If the concentration is equal to or less than the solubility value, the solution is considered saturated. If the concentration is greater than the solubility value, the solution is supersaturated.
