Salinity chemical test kit replacement reagents hanna hi3835-100

The HI3835-100 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate salinity measurements with the chemical test kit. These reagents follow the mercuric nitrate method to determine salinity concentration.

For determination of salinity, the pH of the sample is adjusted to approximately pH 3 with the nitric acid reagent, turning the solution yellow. The mercuric ions present in the titrant react with chloride in the sample. Once all of the chloride is in the mercuric chloride form, excess mercuric ions are present, forming a purple complex with the diphenylcarbazone indicator. The number of milliliters of titrant used to change the solution’s color from yellow to purple will determine the salinity in g/kg (ppt). These reagents are designed to be used with samples that have an expected salinity range of 0 to 40 g/kg (ppt).
