How is cobalt sulphate produced?
Cobalt oxide or other cobalt derivatives are dissolved in dilute sulfuric acid, which crystallizes to form cobalt sulfate. In addition, large amount of cobalt sulfate is produced as a by-product during the manufacturing of various metals, such as nickel and copper.
What happens when cobalt sulphate is dissolved in water?

Is CoSO4 acidic or basic?
An end-chapter problem posed in an 11-grade texbook asks to analyse whether a water solution of CuSO4 will be acidic. The standard answer is yes, because “H2SO4 is a strong acid, hence SO42− is a weak base. As a weak base, it will not be too hot about grabbing H+ from the environment.
Can cobalt have a charge of 4?
Third, there are some exceptions to the previous point. A few elements, all metals, can form more than one possible charge. For example, iron atoms can form 2+ cations or 3+ cations. Cobalt is another element that can form more than one possible charged ion (2+ and 3+), while lead can form 2+ or 4+ cations.
