The salivary bicarbonate concentration is known to increase with increasing flow rate (Dawes 1969). The bicarbonate concentration of gum-stimulated saliva has been reported to increase from an unstimulated value around 4mM (spell out) to a peak of 15mM when chewing a 3 g (spell out) gum sample (Rosenhack, et al, 1993).

Also point out that sodium bicarbonate is baking soda and its purpose is to add carbon dioxide to the solution. Make sure students also know to avoid major veins while hole-punching the leaves. Finally, show students how to remove the syringe plunger and push it until no air is present, only liquid.
Difference Between Bicarbonate and Baking Soda l Bicarbonate vs …
Baking soda is sodium bicarbonate. When combined with moisture and an acidic ingredient (like buttermilk or lemon juice), a chemical reaction produces bubbles of carbon dioxide that expand during baking, causing the batter to rise. This action begins in the bowl, so batters made with baking soda should be mixed and quickly slid into the oven ...
