Question

Use the graph to identify the number, letter, or word that completes each statement.

• The solubility of Solute D
as temperature increases.
• The solubility of Solute
increases the most as temperature increases.
• The solubility of Solutes C and D is the same at
°C.
• As the temperature increases from 0 to 100, which solution’s solubility only changes by about 5 grams? Solution letter:
A graph labeled Solubility versus Temperature for a variety of salts has Temperature from 0 to 100 on the x axis and solubility in grams per 100 grams of water from 0 to 90 on the y axis. 5 solutes from A to E are shown. All data are approximate. Solute A starts at (0, 5), curves up steeply to (30, 50), and declines slowly to (100, 43). Solute B starts at (0, 35) and rises evenly across the graph to (100, 40). Solute C starts at (0, 5) and rises steadily across the graph to (100, 33). Solute D starts at (0, 19), falls to (20, 10), and continues to decline to (100, 0). Solute E Starts at (0, 8), and rises steadily through (40, 48) to (90, 95).

Answer 1

• The solubility of Solute D decreases as temperature increases.
• The solubility of Solute E increases the most as temperature increases.
• The solubility of Solutes C and D is the same at about 30°C.
• Solution letter: B (changes by about 5 g from 0 to 100°C).
