The high potassium in fig is beneficial not only to patients of hypertension but also prevents the bones from rapid thinning by neutralizing the increased urinary calcium loss. Significant correlations were found between iron and potassium, copper and potassium and zinc and copper (p<0.05).
Iodine Global Network (IGN) - Iodate or iodide?
Iodine is dissolved in potassium hydroxide solution and the potassium iodide so obtained is electrolytically oxidised in an annular flow cell. At the end of the electrolysis, the electrolyte is cooled and potassium iodate is obtained.Approximately 80% of KIO3 crystallizes from the reaction mixture.
