General description

Sodium nitrate is synthesized by treating nitrite with nitric acid. The proportion of nitrite production is higher when synthesized by absorbing waste gases from nitric acid.[42] Supplementation of sodium nitrate may serve to improve acute heart failure (AHF) by modulating the nitric oxide precursor levels.[43]

Application

Sodium nitrate has been used:
  • in combination with beef extract for virus elution from water samples
[44]
  • as an external calibrant in nitrate assay to quantify nitrate in cell culture medium
  • [45]
  • as a component of liquid BG11-medium for culturing Synechococcus elongatus PCC 7942
  • [46]
  • to test its protective effects in hepatic ischemia-reperfusion injury
  • [47]
