Baking soda to cancel acidity?
I regularly use baking soda for that purpose to protect what is remaining of my enamel. To allow for the increase in volume as a result of any foaming, use a large container so that the top of the liquid does not go higher than the 3/4 mark.

It is also advisable to leave it overnight in the fridge to let the baking soda dissolve completely.

The taste is slightly saltier. You may want to start with a ratio of a teaspoon to a liter of fluid.
