Description
Part 4500-H+ pH Value
Measurement of pH is one of the most important and frequently used tests in water chemistry. Following an introductory discussion (A), one method is given for the measurement of pH. This electrometric method (B) is described in detail. A general discussion of the principle on which the method is based, and interferences encountered, is followed by a description of apparatus and procedure, including sections on troubleshooting and precision and bias. A table gives the weight of chemicals needed per 1000 mL aqueous solution at 25oC to prepare various pH standard solutions. A second table gives standard pH values at various temperatures, including primary and secondary standards.
