Sodium bicarbonate is NaHCO3
It bubbles in the presence of an acid because it is a base and the acid neutralizes it releasing CO2 gas.
Alka seltzer is a combination of sodium bicarbonate and citric acid. They neutralize each other when added to water.

Sodium bicarbonate is the chemical compound with the formula NaHCO3. Because it has long been known and is widely used, the salt has many other names including sodium hydrogen carbonate and "sodium bicarb," as well as baking soda, bread soda, cooking soda, saleratus, or bicarbonate of soda. It is soluble in water. This white solid is crystalline but often appears as a fine powder. It has a slight alkaline taste resembling that of sodium carbonate. It is a component of the mineral natron and is found dissolved in many mineral springs. It is also produced artificially.
Treatment of sodium bicarbonate with an acid, releases carbon dioxide and water, this is what makes it bubble:
NaHCO3 + HCl â NaCl + H2O + CO2 (gas)
NaHCO3 + CH3C(O)OH â NaO2CCH3 + H2O + CO2 (gas)

It reacts with an acid and gives off CO2 (NaHCO3). AlkaSeltzer has dry acid with the dry sodium bicarbonate.

is a compound composed of sodium and bicarbonate (the name says it all, no?)
carbon dioxide gas floats to the surface and makes it fizzle as it is released.

Its formula is NaHCO3.
When heated, it decomposes to relase CO2 gas. That's why its called baking soda and makes a cake rise.
