Answer: Option (D) is the correct answer.
Explanation:
A dissociation reaction is a reaction in which in which a compound splits or dissociates into its ions.
For example, \(Ca_{3}(PO)_{4} \rightarrow 3Ca^{2+} + 2PO^{3-}_{4}\)
Whereas when two elements combine together and results in the formation of a single compound then it is known as synthesis reaction.
For example, \(C + O_{2} \rightarrow CO_{2}\)
On the other hand, when \(NH_{3}\) is dissolved in water then it gives ammonium and hydroxide ions.
Thus, we can conclude that out of the given options \(Ca_{3}(PO)_{4} \rightarrow 3Ca^{2+} + 2PO^{3-}_{4}\) is an example of dissociation.
