Title: Sodium citrate and Aluminum lactate
Post by: snowlery on September 10, 2021, 02:41:54 AM

Hello, I am not a chemist but I have a question for which I cannot find any answer:

If you put together aluminum lactate and sodium citrate, is it possible that some aluminum citrate and some sodium lactate will be formed?

Please, could you help me with any answer you could have?

With best regards

If you dissolve them in water you get a mixture of the ions. I dont know if aluminium citrate is water soluble, if not it will precipitate. Can you explain what you want to make? Maybe there is a better way.

First thing first: as long as these substances are just dissolved speaking of their identities doesn't make much sense. They dissociate, so the solution doesn't contain salts per se, just ions.

Solution prepared by dissolving sodium chloride and potassium iodide is identical to the solution prepared by dissolving sodium iodide and potassium chloride (assuming you paid attention to concentrations). It contains Na⁺, K⁺, Cl^- and I^-. That's exactly the same type of situation.

If you evaporate the solution to crash out salts, they can precipitate in some specific order, which can be to some extent equivalent to doing the metathesis reaction.

I did mention that they become ions?

Yes, I just added a dot over "i" ;)

@OP, do you know what chelation means?
