Q. Which chemical law proposes that ‘soft drinks and soda bottles are sealed under high pressure to increase the solubility of CO2’? Answer:
Henry’s law
Notes:
According to Henry's Law, the solubility of a gas in a liquid is directly proportional to the pressure of the gas.
So in order to increase the solubility of CO2 in soft drinks, the bottle is sealed under high pressure.
Henry's law is one of the gas laws, formulated by the British chemist, William Henry, in 1803.
