– How does Emergen-C make flat water fizzy?

Question

Is it considered “carbonated”? How is a powder able to add fizz to still tap water? Are there other “instant sodas”?

In: Chemistry

Answer 1

Fizz is carbon dioxide. Instead of adding it as a gas you can make it in situ. One way is to react sodium bicarbonate with an acid like citric or tartaric acids, both of which are solids.
