Baking soda is NaHCO~3~ , Washing soda is Na~2~CO~3~
Baking soda is (incorrectly) called "Bicarb" because there is twice as much Carbonate (CO~3~) per Sodium (Na). Heating it causes some to be released as water and carbon dioxide:
2 NaHCO~3~ → Na~2~CO~3~ + H~2~O + CO~2~
Awesome! I wouldn't call this "releasing moisture" though which, to me, implies a physical change. It's straight up providing the activation energy for a chemical decomposition.
