Permanganate titration with potassium permanganate solution (kmno4) as standard solution is one of the oxidation-reduction titration methods. Kmno4 is a vigorous oxidant in an acidic solution, and its electrode reaction and standard electrode potential φ are as follows, mno4- + 8h+ mn2+ + 4h2o.
Potassium added during processing is generally as potassium chloride. Most of the ingested potassium (80-90%) is excreted in urine, the rest being excreted in faeces and sweat (holbrook et al 1984, pietinen 1982). Potassium filtered in the glomeruli of the kidney is mostly reabsorbed.
