If the pH is higher than desired, adjust it using a hydrochloric acid solution.
Thus, if you need the solution to read the pH as 8.0 which is lower than 9.5, add HCl solution to it.
pH stands for potential of H+ ions, i.e the amount of Hydrogen ions in a solution.
pH is measured on a scale of 0-14, 7 is the neutral point. pH range below 7 is acidic and higher than 7 is basic.
pH is calculated from the formula-
pH= -log10[H+]
We can also measure the Ph levels by a pH meter. It is used for accuracy, reproducibility and continuous measurement. The values are measured in mV and then converted to pH values.
