A solute is a minor component of a solution. For example, if a small amount of benzoic acid is dissolved in diethylether, the benzoic acid is considered to be the solute. If you had 2 solutes (like napthalene and sodium bicarbonate), in which layer would you find each solute? Why?
Predict what will be observed in each experiment below. experiment 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. predicted observation (choose one) 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. O I need more information to predict whether and how much precipitate will form in Sample #2. A student has two unopened 33 cL cans containing carbonated water.
