Inside the presence of sulfuric acid, silver sulphate, and mercury sulphate, potassium dichromate oxidises the organic and natural matter contained within the water sample to provide carbon dioxide (CO2) and water (H2O). The level of potassium dichromate utilised is decided by comparing the volumes of ferrous ammonium sulphate consumed during blank and sample titrations.
This returns any condensation to the reacted sample. Tend not to invert the vial straight away before inserting to the instrument. It's important to allow time for undissolved particles to settle to the bottom and from the light path of the digital instrument.
