I had a similar experience with cobalt sulfate. The material I received was a fairly fine powder, which dissolves in water, but the solution is not
entirely clear. On standing for a day, I get a clear rose/red solution with a very thin layer of solid matter, settled on the bottom.
I also intend to recrystallize the cobalt sulfate. You wrote you used dilute H2SO4. What concentration of the acid did you use and what concentration
of cobalt sulfate did you use?
