We are preparing ferrites ( NiZnFe2O4, MgZnFe2O4, etc.,). After preparing solution we are adding NaOH to get precipitation. Could someone please explain the chemistry behind it? When I took EDS spectra for the sample I did not find Na or H elements - where do these elements go?
solutions get precipitated when the repulsion between the solutes is decreased or vanished. pH play very important role in precipitating solution as with pH the charge on the solute changes. sometimes solute makes stable insoluble or less soluble compounds upon gain of hydrogen or hydroxyl ions.
Dear Vivek Singh sir,
Thank you for your answer.
Can you give any reference.?
Dear Raju Panthagani,
This is simple biochemistry phenomenon and written in various books of biochemistry. You can find references in anlytical biochemistry books or even search it online. these reading could be helpful.
