The remaining barium ions are titrated with ethylenediaminetetraacetic acid disodium solution at pH 10. In titration, not only excess barium ions are titrated by ethylenediaminetetraacetic acid disodium solution, but also calcium and magnesium ions in the raw water are titrated simultaneously. Therefore, the total hardness in the water sample should be included in the calculation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePerformance parameters\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"border-collapse: collapse; width: 100%;\" cellspacing=\"0\" cellpadding=\"8\" border=\"1\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #f5f5f5;\"\u003e\n\u003cth\u003eTechnical Specifications\u003c\/th\u003e\n\u003cth\u003eParameter Values\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Method\u003c\/td\u003e\n\u003ctd\u003eNational Standard Titration Method\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExecution Standard\u003c\/td\u003e\n\u003ctd\u003eDZ\/T 0064.64-93\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Range\u003c\/td\u003e\n\u003ctd\u003e10.00~8000.00 mg\/L\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Period\u003c\/td\u003e\n\u003ctd\u003e≤100 minutes (Depends on sample concentration; higher concentration requires longer detection time)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrecision\u003c\/td\u003e\n\u003ctd\u003e≤10% F.S.

In the online detection instrument for methyl orange acidity, titration method is used to measure the acidity of methyl orange in water samples. It relies on the chemical reaction between two solutions and the color change of the indicator to determine the titration endpoint. Methyl orange, as an indicator, can sensitively reflect changes in the concentration of hydrogen ions in a solution through color changes. At the endpoint of titration, the color of methyl orange will change, indicating that the reaction has reached the predetermined acidity value. During the titration process, a standard alkaline solution of known concentration (such as sodium hydroxide solution) is slowly added dropwise to the water sample to be tested. With the addition of alkaline solution, the hydrogen ions in the water sample are neutralized, and the color of methyl orange gradually changes. When the color of methyl orange changes from yellow to orange (or from red to yellow, depending on the specific pH range and the color change point of methyl orange), it is considered that titration has reached the endpoint. At this point, the volume of standard alkali solution consumed can be used to calculate the acidity of methyl orange in the water sample.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePerformance parameters\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ctable border=\"1\" cellpadding=\"8\" cellspacing=\"0\" style=\"border-collapse: collapse; width: 100%;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #f5f5f5;\"\u003e\n      \u003cth\u003eTechnical Specifications\u003c\/th\u003e\n      \u003cth\u003eParameter Values\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMeasurement Method\u003c\/td\u003e\n      \u003ctd\u003eNational Standard Titration Method\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eExecution Standard\u003c\/td\u003e\n      \u003ctd\u003eGB\/T 9736-2008, GB\/T 258-2016, GB 5009.239-2016\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMeasuring Range\u003c\/td\u003e\n      \u003ctd\u003e0.00 mmol\/L ~ 10.00 mmol\/L (range customizable)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMeasuring Period\u003c\/td\u003e\n      \u003ctd\u003e15 minutes\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePrecision\u003c\/td\u003e\n      \u003ctd\u003e≤5% F.S.
