Yes if a carbonated soda is left out for a long time while it is open the fizz will dissolve into the air thus making the beverage flat. :)
No, both sodium carbonate (washing soda) and sodium bicarbonate (baking soda) are solids.
Baking soda is sodium hydrogen carbonate-NaHCO3.
the chemical formula of washing soda is Na2CO3 (Sodium carbonate).
Baking soda is sodium bicarbonate, NaHCO3, and it contains carbon.
washing soda = sodium carbonate
sodium carbonate
Na2CO3 is commonly known as Sodium Carbonate.
it is commercially known as soda ash.
To carbonate soda, carbon dioxide gas is dissolved into the liquid under pressure. This process creates the fizzy bubbles that give soda its characteristic effervescence.
"Flat" soda, defined as former soda from which all of the dissolved carbon dioxide used to carbonate water, would usually be a mixture, because it would contain flavoring agents as well as water. Flat seltzer water, however, could be a single substace: pure water.
Baking soda is sodium bi-carbonate. Or sodium hydrogen carbonate. Its formula is NaHCO3. It is a union of sodium and the bi-carbonate polyatomic ion.
Baking soda can be transformed into sodium carbonate through a process called heating or calcination. When baking soda is heated at a high temperature, it undergoes a chemical reaction that converts it into sodium carbonate.
