Method for determining sodium chloride content by mercury titration
Thread Content
In chlor-alkali plants, the salt content in saturated brine is determined. Previously, we used the silver method; however, towards the end of the year it became difficult to obtain explosives, so we want to switch to the mercury method, using mercuric nitrate for determination. We are seeking specific procedures from those who work in this field.

In fact, using a constant-temperature water bath for accurate density measurements to convert it into saltwater concentration is also very reliable.
It is a central control project that requires rapid measurement; accuracy at the level of g/L is generally sufficient
With precision to grams per liter, a regular float density gauge is sufficient; add a thermometer as well to adjust the measurement values using the temperature reading.
