Measuring Hydrogen Peroxide Concentration
Method for measuring the concentration of hydrogen peroxide
Those who measure the concentration of hydrogen peroxide must have their own method. At the beginning of the method, prepare a number of instruments, which are clean and good. Take an appropriate amount of liquid containing hydrogen peroxide and place it in a purifier.
Then, choose the appropriate agent. Such as potassium iodide, put it in the liquid, see its response, and a chemical change occurs. The change also produces iodine elemental substance, and the color of the liquid gradually changes.
Compound with droplets of sodium thiosulfate. When dripping, observe the change of liquid color until the color is nearly colorless, and does not change again for half a minute, stop dripping. Remember the amount of sodium thiosulfate liquid.
According to chemical principles, according to the reaction formula, calculate the ratio of sodium thiosulfate to hydrogen peroxide. Knowing the amount of sodium thiosulfate, the concentration of hydrogen peroxide can be deduced.
When measuring, be careful, the equipment must be clean, the amount must be accurate, and the inspection must be careful. If there is a slight difference, the result will not be accurate. Although this method is ancient, according to chemical principles, it can be confirmed that the concentration of hydrogen peroxide is accurate for all kinds of users, which is beneficial to all things.
