Question
Bottled soda water is produced by increasing the gas pressure and carbon dioxide content. For a bottle having a total gas pressure of 2 atm, determine the pH of the soda water at 25-degree Centigrade. The composition of gas in the head space above the soda water is 95% percent carbon dioxide by volume.
