Will CO2 escape from soda if you vacuum seal it?

Well, the amount of gas that can be dissolved in a liquid is dependent on temperature. The lower the temperature the higher the amount of gas that can be dissolved. And if you hermetically seal a soda bottle it possible to keep the C02 from escaping. Depends on temperature, but in room temperature: It won´t escape until you remove the seal. What happens when you vacuum seals is that you remove all the air, which results in low pressure. Low pressure equals low boiling point. The CO2 in the H2CO3 solution will vaporize but stay in the bottle.
