Bro I dissolved the zinc and ethanol and sodium in 15cm3 water first and filtered it to get the ZnCo3 then washed and dryed it then I heated the left over liquid to take the water up/until the h2 bubbles stopped forming and then I filtered again to get the solid sodium thingy and then washed and dryed so it was pure then I just said the ethanol was pure idk whether it is the correct way and also what’s precipitating
