If 22 grams of water are saturated at 75 degrees celsius with potassium nitrate and then cooled to 40 degrees celsius, how much will precipitate?
To determine how much potassium nitrate precipitates when the saturated water is cooled, we need to compare the solubility of potassium nitrate at both temperatures.
One way to find this information is to consult a solubility chart or reference material. Alternatively, we can use an online database or search for a solubility curve specific to potassium nitrate.
Once we have the solubility data, we can compare the solubility of potassium nitrate at 75 degrees Celsius with that at 40 degrees Celsius. If the solubility at 40 degrees Celsius is lower than the amount of potassium nitrate originally dissolved at 75 degrees Celsius, then precipitation will occur.
By calculating the difference between the initial amount of potassium nitrate dissolved in the water and the amount that remains soluble at 40 degrees Celsius, we can determine how much potassium nitrate will precipitate.
I will now search for the solubility data for potassium nitrate at different temperatures.
