How can I synthesise nanoparticles of cobalt carbonate with chemical precipitation method from cobalt ion and sodium carbonate solutions?
Prepare two solutions of cobalt and sodium carbonate in water with a molar ratio of 1:2.1 separately. You need some excess sodium carbonate. Then you can take cobalt solution in a vial and put it under sonication. Add sodium carbonate while it is sonicating.

Hi,Noureen Siraj ,Thanks for your answer , Is the molar ratio 1:2.1(one to two point one)?
Take Cobalt nitrate and sodium carbonate in appropriate staichiometric ration by using their density values and solubility in the water. Generally, you should take sodium carbonate more than precursor. The preferred ration is 1 cobalt nitrate : 2 sodium carbonate and continue this reaction under sonicator. Hope best for u
yes one to two point one. you need little bit excess amount of sodium carbonate.
Hi,Noureen Siraj ,Thanks for your answer, Excuse meو are concentrations in mol/lit unit. Thanks
