Question

When you open a bottle of a soft drink and leave it open, the drink eventually goes flat. this happens because the equilibrium between carbonic acid and carbon dioxide shifts to produce?

Answer 1

The biting sensation you get from drinking a cold softdrink is due to the dissolution of carbon dioxide in the solvent in the form of carbonic acid. As temperature increases, the carbon dioxide escapes the solvent, thus, the flat taste. So, this happens because the reaction favors the forward reaction toward the carbon dioxide,
