Buffer solution pH 10.00
A buffer solution with a pH of 10.00 is primarily used in a lab to calibrate pH meters and electrodes and as a control standard for measuring the pH of other basic solutions. It is also used in specific chemical applications such as EDTA titrations for complexometry, which requires a stable, basic environment.
Buffer solution pH 10.00 Common uses:
pH Meter Calibration:
The most common use is to set a known pH value on a pH meter or probe, ensuring accurate measurements for other solutions.
Quality Control:
It acts as a standard to check if a pH instrument is working correctly before or after measuring unknown samples.
EDTA Titration:
A pH 10 buffer provides a stable, alkaline medium necessary for the complex formation between metal ions and EDTA, as well as for achieving the correct color change with indicators like eriochrome black T.
Important Considerations:
Temperature Dependency:
The actual pH of the buffer solution can change with temperature, so it is crucial to maintain a constant temperature during its use.
Stability:
Some buffer solutions, particularly those absorbing carbon dioxide from the air, can become unstable and less accurate over time.
