Study Notes
Chemical Waste Labeling
- A chemical waste label requires four essential pieces of information: the names of all chemicals and their compositions, the date the first chemical was added to the container, the name of the person responsible, and the laboratory where the waste was produced.
Equivalence Point
- The equivalence point is the point at which the amount of titrant added equals the amount of analyte present, indicating the completion of the reaction.
pH Measurement
- pH is measured using pH electrodes, which are analytical sensors that determine the potential of hydrogen (pH) or the negative logarithm of the hydrogen ion activity in a solution.
- If the H+ density is higher than OH-, the substance is acidic, with a pH less than 7.
Types of pH Meters
- Laboratory pH meters are multi-function and high-accuracy devices.
- Industrial online pH meters are characterized by excellent stability, steady work, a specific level of measurement efficiency, and environmental flexibility.
