Q:
Hello, I was wondering if you put an effervescent tablet and water in a pressurised chamber and gradually increased the pressure inside, would the tablet eventually stop dissolving and producing gases (before it has completely dissolved)?

A:

Yes, in principle if you raise the pressure of CO2 enough the equilibrium would no longer favor further dissolving. Whether that's close to being reachable in practice, I'm not sure.
