A glass electrode was determined to have a potential of 0.395 V when measured against the SCE in a standard pH 7.00 buffer solution. Calculate the pH of the unknown solution for which gives the potential reading of – 0.013 V. The potential decreases with increasing pH. Assume Nernstian response at 25 °C.
