alleryTo increase the solubility of CO₂ in soft drinks, manufacturers:
ASeal the bottle under high CO₂ pressure
BHeat the solution
CAdd salt
DUse a non-polar solvent
Answer & Solution
Correct answer: A. Seal the bottle under high CO₂ pressure
Higher partial pressure of CO₂ above the liquid
→ more dissolved CO₂ (Henry's law).
That's why soda bottles are **sealed under high CO₂ pressure** and fizz on opening (pressure drop → CO₂ escapes).
