But would the reaction be the same if i swithed s2so4 till so4 2.

[moeliya]

  2Cl- +  CoCl2 (aq)   ==>[CoCl4]2-   (aq)
  4Cl- +  Co2+(aq)   ==>[CoCl4]2-   (aq)
is these two the same reaction ??

Sorry for the *Ignore me, I am impatient* but guys when Cocl  react with So4 (2-) the reaction will be a Precipitation and you will have a solid Coso4 (s) but how do I write the equation balanced ?

[magician4]

CoSO₄ , due to my information, has an excellent solubility in water (esp. for a 2/2 salt) of 383 g/ L at 25°C

  there will be no precipitation of CoSO_4(s), therefore no balanced equation for this nonexistent process is required

might it be that you're confusing things, and are thinking of CaSO₄ (which is a completely different story?)
