Question

A freshman chemistry student decides to examine the soda fountain methods of making carbonated beverages by measuring the amount of acid in a fixed volume Coca-Cola. He/she decides that he/she will use a 250 ml sample for all of his/her analyses and that he/she will make each batch with a separate CO2 cylinder so that carbon dioxide content in each batch would be as uniform as possible. In a typical experiment, the student saturates the Coke solution with the CO2 in the cylinder. He/she titrates the 250 ml sample to phenolphthalein endpoint with 7.65 ml of a sodium hydroxide solution that contains 5.670 grams of sodium hydroxide per liter. How much carbon dioxide was in the saturated solution?

Answer 1

6.5 g/l
