Consider this .... sufuric acid and lye. By themselves, either one is
really
bad, but mixed together in the correct ratio, and you get a fairly safe
result.
2 NaOH + H2SO4 ---> Na2SO4 + 2 H20
... and, IIRC, sodium sulfate isn't terribly dangerous. One MSDS can be
viewed here: http://www.gileschemical.com/tech/na2ssads.htm
Another one ... muriatic (or hydrochloric) acid
HCl + NaOH ---> NaCl + H20
that would be salt (NaCl) and water.
However, I wouldn't drink the results from the mix of two industrial-grade
chemical sources, even after the pH (acid/caustic) was neutralized. The
unknown impurities (likely heavy metals) would probably be bad news.
