Presence of sodium carbonate not interfere in COD measurement

Rens Brouwer

Ashokkumar V. Rajani Thank you very much!

Phani Bhusan Ghosh

The amount of strong H2SO4 added during COD estimation is total volume of sample plus pot.dichromate and if sodium carbonate is there, a very negligible amount of acid would be consumed and it will not affect the analysis of COD measurement anyway.
