Related Questions for Experiment 6 1. Use the CRC Handbook of Chemistry and Physics to find the solubility of carbon dioxide in water. It will be in the section "Physical Constants of Inorganic Compounds" of the 75th (1994-95) edition or earlier editions. This information can also be found in the Merck Index. Solubility in cold water (0°C) cm3 CO2 per 100 cm3 H,O a. b. Solubility in hot water (20°C) cm3 CO2 per 100 cm3 H,o Solubility in cold water (0°C) g CO2 per 100 cm3 Solubility in hot water (60°C) g CO2 per 100 cm3 This difference seen in solubility at different temperatures is typical of gases. How does increasing temperature affect the solubility of a gas in water? c. d. e.Explanation / Answer
Carbon dioxide becomes less soluble in water as the temperature increases.
THe solubility af the 20 degrees is 0.1688 and the solubility at the 60 degrees is 0.0576 per 100 cm3 of H2O.
The solubility of solutes is dependent on temperature. When a solid dissolves in a liquid, a change in the physical state of the solid takes place. Heat is required to break the bonds holding the molecules in the solid together. At the same time, heat is given off during the formation of new solute -- solvent bonds. Thus the two types of situation pertains
