what does combining white vinegar and baking soda
Baking soda is alkaline, a base, with a pH of around 8.1. Vinegar is acidic, and most commercial distilled white vinegars contain 5 percent acetic acid and has a pH of about 2.4. Neutral is 7.0. There is one instance when I recommend combining baking soda and vinegar, and that is in the drain. Sometimes the bubbling and hissing in the drain when you combine these two is enough to dislodge hair and gummy buildup. (I recommend a cup of baking soda down the drain, followed by a cup of vinegar.)
