Yes, you are right in that the sodium citrate by itself has
completely dissolved the ferric citrate. After seeing your message
above I went back and added an extra 3g of sodium citrate to the
solution (now 10g of ferric citrate + 13g of sodium citrate in 35ml
of water) and everything has now dissolved. I should be able to test
the solution very soon.
