Popular questions
  1. Is potassium bicarbonate good for you?

    In the small amounts used in foods, potassium bicarbonate (E501ii) is generally recognized as safe and can help reduce sodium compared with baking soda. Large amounts may raise blood potassium—people with kidney disease or on potassium‑sparing medications should avoid high intakes.

  2. Is potassium bicarbonate baking soda?

    No—baking soda is sodium bicarbonate (NaHCO3); potassium bicarbonate (E501ii) is a sodium‑free alternative used similarly as a leavening agent.

  3. What are the two sizes of potassium bicarbonate portable extinguishers?

    Common portable potassium bicarbonate (PKP) extinguishers are typically 18‑lb and 27‑lb units.

  4. Is potassium bicarbonate the same as baking soda?

    No—baking soda is sodium bicarbonate, while potassium bicarbonate (E501ii) is the potassium version and a sodium‑free substitute.

  5. What is potassium bicarbonate used for?

    In foods it functions as a leavening/raising agent, acidity regulator, and stabilizer, often as a sodium‑free alternative to baking soda. It’s used in baking powders, low‑sodium baked goods, and to reduce acidity in products like wine and cocoa.

  1. What does baking soda do?

    It’s a leavening agent (sodium bicarbonate) that releases carbon dioxide when it reacts with acids, helping batters and doughs rise. It also raises pH, which can enhance browning and mellow acidity.

  2. What's the difference between baking soda and baking powder?

    Baking soda is pure sodium bicarbonate and needs an added acid to work; baking powder contains sodium bicarbonate plus acidic salts and usually starch. Most baking powders are double-acting, releasing gas when wet and again when heated.

  3. Can i use baking soda instead of baking powder?

    Yes—if you add an acid: for each 1 tsp baking powder, use about 1/4 tsp baking soda plus 1/2 tsp cream of tartar (or an equivalent acidic ingredient like lemon juice, yogurt, or buttermilk). Adjust liquids if using acidic liquids so the batter isn’t too wet.

  4. Does baking soda go bad?

    It doesn’t spoil, but it can lose leavening power after opening, especially if exposed to moisture or odors. For baking, replace about every 6 months after opening or test by adding some to vinegar/hot water—vigorous fizz means it’s still active.

  5. Can i use baking powder instead of baking soda?

    Often, yes: use roughly 3 times as much baking powder as baking soda (1 tsp soda ≈ 3 tsp powder). Because powder already includes acid and starch, reduce other acidic ingredients if needed, and expect slight changes in flavor or texture.
