You say true!
A black goose for you.

The Bi reference was that it can be used to make a substance alkaline or acidic.

The Calvins can use NaHCO3 to absorb musty odors from books and it was used in the Manhattan project when laundering clothes as it removes U oxides from the clothes as U oxides bind VERY well with cotton. Moffit's Solution is used in nasal and other ENT surgeries. It consists of Adrenaline, cocaine and NaHCO3 which serves to make it so the solution doesn't burn too much.
The oven reference is...well try baking a can of soda in your oven. I did...just for this riddle!! I suspect I had too much Moffett's solution.
