Question : Which chemical law proposes that "soft drinks and soda bottles are sealed under high pressure to increase the solubility of CO2?"
Option 1: Dalton’s Law
Option 2: Henry's Law
Option 3: Ohm's Law
Option 4: Raoult’s Law
Correct Answer: Henry's Law
Solution : The correct answer is Henry's Law.
Henry's Law is one of the gas laws formulated by the British chemist William Henry in 1803.
According to Henry's Law, the solubility of a gas in a liquid is directly proportional to the pressure of the gas. So, to increase the solubility of CO2 in soft drinks, the bottle is sealed under high pressure.
