What is a pH standard solution?
pH standard solution is a liquid widely used in chemical and biological laboratories with a known pH value for calibrating and adjusting pH measuring instruments to ensure the accuracy of measurement results. pH standard solutions are mainly used to calibrate pH meters and pH electrodes to ensure that these instruments can provide accurate and reliable pH measurement results. During experiments and analysis, pH standard solutions can be used as control samples to help verify and confirm the accuracy of the pH value measured in the experiment.
Common pH standard solutions
pH 4.01, 7.00 and 10.01 standard solutions: This is a common series of pH standard solutions used to calibrate most pH instruments. Each standard has an exact pH value of 4.01, 7.00 and 10.01.
Things to note when purchasing and using pH standard solutions
When selecting a pH standard solution, you should choose a high-accuracy product provided by the manufacturer to ensure the reliability of the measurement results.
pH standard solutions should be stored in a dry, cool environment away from exposure to air and light to maintain their stability.
pH standard solution is an indispensable calibration and verification tool in the laboratory, ensuring the accuracy and repeatability of pH measurements. When using it, it is necessary to follow relevant laboratory operating procedures and regularly check and update the pH standard solution.
