Solubility changes at different temperatures?

Posted on 2014-04-15 08:01:00 in Chemistry by DEXTER

Thank you to all who help! Can you please show your work? I did most of my chemistry homework, minus these two problems.



1) If 57 grams of KCl dissolve at 100 degrees C, what is the solubility of KCl at 90 degrees C?



2) If 56g of NH4Cl can dissolve at 60C, and I only dissolve 40g of solute, what temperature would the solute begin to fall out of solution?



I know the definition of words. Even a general equation would help. Thank you!
