The problem you have here is that, as I have already mentioned, you are adding much more solvent than you can possibly have of the "remedy" substances (in the case of a "c" preparation, 100 times as much), so that, even if the
solute reacts with the solvent, the end result of the reaction will still be in solution in the solvent, and therefore must be stable with respect to that solvent. So even if your solute reacts with the solvent at the first dilution, the result of that reaction will be something that will not react further with the solvent. There can be no further reaction after the first dilution.
Of course, if your mother tincture is made up using the same solvent as that used for the dilutions (as you have indicated
here, where you describe preparing the MT using water and alcohol) you will not have any reaction even at the first dilution: any possible reaction will already have taken place when you prepared the mother tincture.
