| Abstract: | In this paper, the solubility of Sodium dithionite in Nacl solutions of various
concentration was investigated and an improvement for manufacturing sodium
dithionite by zinc powder was made. Adopting this improved technique, the
yield of sodium dithionite increased by more than 2% and the amount of Nacle
used in salting-our operation decreased by 10%. |
