Question

Use the table to compare the solubilities of substances. Check all of the boxes that apply.

Aspirin is less soluble than table salt, but more soluble than carbon dioxide.

A saltwater solution can be made by dissolving 20 g NaCl in 50 mL water.

A saturated solution of table sugar is more concentrated than a saturated solution of table salt.

Increasing the temperature will increase the solubility of all the solutes in the table
A table has 2 columns and 4 rows. Column 1 is labeled Solute with entries Table Sugar, Upper C Subscript 12 Baseline Upper H Subscript 22 Baseline Upper O Subscript 11; Table Salt, Upper N a Upper C l; Aspirin, Upper C Subscript 9 Baseline Upper H Subscript 8 Baseline Upper O Subscript 4; Carbon Dioxide, Upper C Upper O Subscript 2. Column 2 is labeled solubility in grams per 100 grams of water with entries 200, 38, 0.33, 0.17.

Answer 1

Check statements 1 and 3.

1) True — Aspirin (0.33 g/100 g water) < Table salt (38 g/100 g water) and > Carbon dioxide (0.17 g/100 g water).

2) False — Max NaCl that will dissolve in 50 g water = (38 g / 100 g water) × 50 g = 19 g, so 20 g would not fully dissolve.

3) True — Saturated sucrose (200 g/100 g water) is more concentrated than saturated NaCl (38 g/100 g water).

4) False — solubility does not increase with temperature for all substances (e.g., gases like CO2 usually become less soluble as temperature rises).
