Answer :
The compound cobalt(II) nitrate, Co(NO3)2 is soluble in water. The net ionic equation for the dissociation reaction is Co(NO3)2 (s) = CO2+(aq) + Na3(aq) + PO4-(l).
In general, during the dissociation process in chemistry, molecules (or ionic compounds like salts, or complexes) separate or divide into different entities like atoms, ions, or radicals. This procedure is typically reversible. For instance, the covalent bond between an electronegative atom and a hydrogen atom is broken when an acid dissolves in water due to heterolytic fission, in a reaction which releases a proton (H+) and a negative ion. Dissociation is the antithesis of connection or recombination. Separation of the anions and cations occurs when salts are dissociated by solvation in a solution, such as water. The solvent can be evaporated in order to recover the salt. A substance that has free ions and can be employed as an electrically conducting medium is referred to as an electrolyte. In a weak electrolyte, the majority of the solute does not dissolve, whereas in a strong electrolyte, a higher proportion of the solute dissociates to generate free ions. A weak electrolyte is a material whose solute primarily occurs in solution as molecules (which are referred to as being "undissociated"), with a very tiny amount existing in solution as ions.
