what is yellow iron? in hindi we call it KANTSAR LOHA? PLS TELL ME. — Preceding unsigned comment added by 220.227.46.17 (talk) 03:08, 2 December 2011 (UTC)

Please ask at Wikipedia:Reference desk/Science‎ when the question is not maintainance/edit related. Plasmic Physics (talk) 04:09, 2 December 2011 (UTC)

I fear that the "chemistry section" is rubbish (pH 2-4 is very acidic, there is not much hydroxide present...). iron(III)-hydroxide precipitate at alkaline ph!--188.60.35.246 (talk) 22:40, 26 March 2013 (UTC)

Silly Peroxide reference[edit]

Peroxide does oxidize Ferrous to Ferric ion but also reduces Ferric to soluble Ferrous iron; this is one major way of removing rust stains. Iron salts are CATALYSTS in organic oxidations because they recycle thusly an yield Hydroxyl radicals. 2001:4898:80E8:ED31:0:0:0:2 (talk) 06:19, 15 June 2015 (UTC)

Dissociation constant for Iron Hydroxide would be nice[edit]

Iron, like Chromium, oxidation states are highly pH dependent; this also affects Iron Hydroxide/Oxide formation. [Fe][OH] constant is very high making Iron Hydroxide very insoluble and driving its formation at low p[OH] concentrations. 2001:4898:80E8:ED31:0:0:0:3 (talk) 06:23, 15 June 2015 (UTC)
