A student stated that the solubility of KCl at 20 degrees Celsius was 36 grams of KCl per 100 grams of solution. What is wrong with this statement?
solubility is in moles or grams solute/mass solvent, not per mass solution
Well, I hate to be the bearer of bad news, but that student's statement is as accurate as a penguin wearing a tuxedo at the beach. The solubility of KCl at 20 degrees Celsius is actually closer to 34 grams of KCl per 100 grams of water, not solution. So, unfortunately, that student's math might be as shaky as a Jenga tower after one too many cups of coffee. But hey, we all make mistakes, right?
The statement is incorrect because the solubility of a substance is typically measured in grams of solute per 100 grams of solvent, not per 100 grams of solution. In this case, the solubility of KCl would be stated as 36 grams of KCl per 100 grams of water.
The statement by the student is incorrect because solubility is typically expressed in terms of grams of solute per 100 grams of solvent, not per 100 grams of solution. Solvent refers to the substance in which the solute dissolves, whereas the solution is the combination of solute and solvent.
To correct the statement, it should say that the solubility of KCl at 20 degrees Celsius is 36 grams of KCl per 100 grams of water (assuming water is the solvent).
To identify the correct solubility of a substance at a given temperature, you can refer to solubility tables or datasheets. These resources provide accurate and reliable information on the solubility of various compounds under different conditions.
