In response to Alistair's question on the EDTA use in batteries, my GUESS is that the EDTA functions as a chelator for all divalent ions. EDTA has been used to reduce the activities of metals in solution (Activity refers to the free ion concentration) In lead acid batteries, the lead exists as Pb+2 when it is in solution. Maybe adding EDTA complexes the Pb+2 such that it doesn't react and form the slightly insoluble sulfate salts
it doesn't react and form the slightly soluble sulfate salts whixh can then accumulate and short out the battery..... christian
