Final answer:
Potassium thiocyanate (KSCN) dissociates in water to form potassium ions (K+) and thiocyanate ions (SCN-) in a 1:1 ratio. The balanced dissociation reaction is KSCN(s) → K+(aq) + SCN-(aq).
Step-by-step explanation:
Complete and Balance the Dissociation Reaction
When potassium thiocyanate (KSCN) is dissolved in water, it dissociates into potassium ions (K+) and thiocyanate ions (SCN-). The balanced chemical equation for the dissociation of KSCN in water can be written as:
KSCN(s) → K+(aq) + SCN-(aq)
This process is an example of the dissolution of an ionic compound in water. The equation is balanced as written because there is one potassium ion and one thiocyanate ion on the product side, which corresponds to the single K+ and SCN- in the KSCN formula unit.
