Hi. I arrived at this question because I found a some sites offering supposed homemade household cleaner mixtures but was concerned that the ingredients may counteract each other. I was warned for posting this in the Chemistry discussion forum, but the question is not related to coursework. 1. The problem statement, all variables and given/known data I was wondering what mixture results when adding Borax to Vinegar, and what reaction if any occurs. 2. Relevant equations Borax - Na2 B4 O7 Acetic acid - C2 H4 O2 1 tsp borax 2 tsp vinegar 3. The attempt at a solution My guess is that the low pH of the acetic acid will be partially neutralized by the high pH of the borax. The resulting mixture would be a weaker acid or a weaker base, depending on whether an excess of borax or an excess of vinegar was present. In a related question, I'd be curious to know how to figure out which product would be favored in this reaction, and possibly what the pH of the resulting solution would be.
