pH standard solutions have known pH values with specified accuracy, good reproducibility and stability, high buffer capacity, small dilution values, and low temperature coefficients. They are commonly used for the calibration of pH meters (both zero and slope adjustments), with an accuracy range of ±0.01 pH.
