LIKE DISSOLVES LIKE - Purdue University
Reduce all iodine species to iodide by shaking the mixture with sodium thiosulfate until the mixture is colorless. Separate the aqueous phase from the organic solvents. Flush the aqueous phase down the drain with plenty of water. Dispose of the solvents as hazardous waste, according to your state and local

The Fermentation of Pyruvate - Purdue University
www.chem.purdue.eduundergo lactate fermentation. Two pyruvates are converted to two lactic acid molecules, which ionize to form lactate. In this process two NADH + H+ are converted to two NAD+. Our muscle cells can undergo this process when they are in oxygen debt. If enough oxygen is not present to undergo aerobic respiration, pyruvate will undergo lactic acid
