Muhtasari mfupi
Kikundi cha michanganyiko ya sulfate ya Cobalt ni pamoja na vitu yoyote visivyo na fomula CoSO4 (H2O) x. Mara nyingi hata hivyo sulfate ya cobalt inahusu hexa- au heptahydrates CoSO4.6H2O au CoSO4.7H2O, hawa. Kwa kuonekana, heptahydrate ni imara nyekundu. Inumunyuka katika maji na methanol. Pia haina harufu. Kwa sababu sulfate ya cobalt ina idadi ya kawaida ya elektroni, chumvi zake ni paramagnetic katika asili.
Mchakato wa Viwanda
Siku hizi, njia ya kawaida ya utengenezaji sulfate ya cobalt kwa kiwango kikubwa na kwa kiasi kikubwa ni kutibu oksidi ya kobalti na asidi ya sulfuriki. Njia nyingine hutumia kobalti badala ya oksidi yake. Zifuatazo ni athari za kemikali: Co + H2SO4 + 7 H2O → CoSO4 (H2O) 7 + H2 CoO + H2SO4 + 6 H2O → CoSO4 (H2O) 7
