I need some help because I dont know what happens in this reaction. I have to write a description for this reaction like what color the fluid get or why it have a specific color.
The reaction equation is: Co(CH₃COO)₂*4 H₂O+ 4 KOCN → K₂[Co(NCO)₄]+ 4 H₂O +2 K(CH₃COO)
I only know that K₂[Co(NCO)₄] is a blue Precipitation after a cooling time.

It is a built up of a Cyanatocomplex with cobalt. Nothing special.
