It’s odd how the article ends with “Baking soda also interact with acidic ingredients like buttermilk and cocoa in cakes and other baked goods to help the batter expand and, along with heat from the oven, to rise. It can also help raise the pH in pools, is found in antacids and can help clean your teeth and tub.” Was this also sponsored by the baking powder trade association or something?
I recently became more aware of the uses of baking soda and searched online for a list of what people did with it. Same thing with Vaseline another time. Both times you get these weird article written by so-called mothers who list over fifty different uses (not that different, and many dubious, or with obvious unwanted side effects). It's a bit creepy.
