Explain how high pressure allows for the successful production of sparkling water. Note that the solubility of carbon dioxide in water is 0.169 g/100 mL at standard temperature and pressure (1 atm, 25 °C).

• A. High pressure increases the solubility of carbon dioxide in water to form carbonic acid.
• B. High pressure decreases the solubility of carbon dioxide in water so that gases stay in the headspace of the closed container.
• C. High pressure maintains the solubility of carbon dioxide at its standard level.
• D. High pressure is not an important factor in the successful production of sparkling water.

Answer: (A)
