For example, the label of a household bleach product may specify "5% sodium hypochlorite by weight." That would mean that 1 kilogram of the product contains 0.05 × 1000 g = 50 g of NaClO. A typical oxidation reaction is the conversion of iodide I − to elemental iodine I 2. The relevant reactions are NaClO + 2 H + + 2 I − → NaCl + H 2 O ...
Bactericidal action via a so-called oligodynamic effect in which small amounts of heavy metals such as bismuth damage many different bacteria species. Weak antacid properties In vitro and in vivo data have shown that bismuth subsalicylate hydrolyzes in the gut to bismuth oxychloride and salicylic acid and less commonly bismuth hydroxide .
