A pair of 100mL samples of water are taken from a well bored into a large underground salt NaCl deposit. Sample #1 is from the top of the well, and is initially at 32°C. Sample #2 is from a depth of 50.m, and is initially at 42°C. Both samples are allowed to come to room temperature (20.°C) and 1atm pressure. An NaCl precipitate is seen to form in Sample #1.
a. A bigger mass of NaCl precipitate will form in Sample
b. A smaller mass of NaCl precipitate will form in Sample
c. The same mass of NaCl precipitate will form in Sample #2.
d. No, precipitate will form in Sample #2.
e. I need more information to predict whether and how much precipitate will form in Sample #2.
