How do i make iron citrate?

Answer 1

Although citric acid is a weak binder of iron, coordination is possible if enough of the citrate is available to push the equilibrium towards binding Fe(III). I would probably add 50:1 ratio of citrate:iron in water. So, if you start with 1 mol of iron (III), add 50 moles or more of citrate to assure that all the iron is chelated. In addition, it's preferable to add the citrate in its disodium form, although citric acid by itself should still bind to the iron. If you start with citric acid, you can add 2x moles of NaOH to form the disodium form of citrate. Always add the ligand first (i.e. the citrate) to water then add the iron. Adding the iron first may cause it to precipitate as iron hydroxide (rust) and will probably be unavailable for the citrate.

Answer 2

To make iron citrate, you can dissolve iron carbonate or iron oxide in citric acid solution. You can then neutralize the solution with sodium hydroxide to form iron citrate precipitate, which can be filtered and dried to obtain the final product. Make sure to handle the chemicals safely and maintain proper pH conditions for the reaction.

Answer 3

You dig up iron ore and melt the stone around it, so you can mold it into iron stuff.
