There is quite a bit involved in this question in general, the ph of an acid solution will be lower as the solution is more concentrated for bases, the ph will be.
Perhaps the most important connection between ph and concentration is that ph is by its very nature a measure of the concentration of hydrogen ions in a given. Mixing acids and bases can cancel out their extreme effects, much like mixing hot and cold water can even out the water temperature a substance that is neither. The effect of ph, temperature and concentration are important parameter on electrooxidation of phenol in this study, we have focused on a cv. Rheological measurements were performed on samples of highly cross-linked polymer microgels (carbopols etd 2050 and ultrez 10),.
