Question
**Title: Understanding Precipitation in Salt Deposits** **Description:** Two 250 mL samples of water are drawn from a deep well bored into a large underground salt (NaCl) deposit. Sample #1 is from the top of the well, and is initially at 42 °C. Sample #2 is from a depth of 150 m, and is initially at 8 °C. Both samples are allowed to come to room temperature (20 °C) and 1 atm pressure. An NaCl precipitate is seen to form in Sample #1. **Question:** Given these conditions, what is likely to happen with Sample #2? - ○ A bigger mass of NaCl precipitate will form in Sample #2. - ○ A smaller mass of NaCl precipitate will form in Sample #2. - ○ The same mass of NaCl precipitate will form in Sample #2. - ○ No precipitate will form in Sample #2. - ○ I need more information to predict whether and how much precipitate will form in Sample #2.

A student wants to make two batches of rock candy. He finds an unopened box of "cane sugar" in the pantry. He starts preparing batch A by dissolving sugar in 500 mL of hot water (70 °C). He keeps adding sugar until no more sugar dissolves in the hot water. He cools the solution to room temperature.
