Like salt. Even the usual one, NaCl, dissolved in water and electrolyzed, dissipates to NaOH, NaOCl, HCl, H2 and Cl2. HCl, H2 and Cl2 are gaseous, so they bubble out, but NaOH (lye) and NaOCl (bleach) stays in solution.

And that's just one example, there's multitude of other chemicals that's produced by electrolysis, potentially making water toxic.
