In this case, that is usually the pH buffer and you then control the difference. If you end up adjusting the pH electrode, then you ultimately correct the current measurement value to a reference value which is normally the one printed on …

The concen used were 1-0.01 M and my pH meter said the range is from -0.6 to 1.7, actually. In the literature the pH of the chromic acid solution is often related to the size of the polyanions that can be found. Which is important to us.
WebbpH measurements have been, and continue to be, widely used as a rapid, accurate measure of the acidity of fluids of all sorts.
