In the equation:
Fe(NO3)3 (aq) + 3KSCN (aq) forms FeSCN3 (aq) + 3KNO3 (aq)
What type of reaction is this? why are there two aqueous solutions as products? Is there a secondary reaction? Finally is there a name for these products?
This equation represents a double displacement reaction, specifically a combination of a precipitation and an exchange reaction.
To determine the type of reaction, it is helpful to identify the reactants and products involved. In this case, Fe(NO3)3 and KSCN are the reactants, and FeSCN3 and KNO3 are the products. A double displacement reaction occurs when the positive ions of one reactant switch places with the positive ions of the other reactant to form new compounds.
The presence of "aq" (aqueous) indicates that the reactants and products are dissolved in water. In this case, both Fe(NO3)3 and KSCN are soluble in water, hence they are represented as aqueous solutions. The products, FeSCN3 and KNO3, are also soluble in water and are shown as aqueous solutions.
There is no secondary reaction present in this equation. It is a straightforward combination of the reactants to produce the products.
The products, FeSCN3 (ferric thiocyanate) and KNO3 (potassium nitrate), each have their own names. Ferric thiocyanate refers to the compound that is formed by the reaction between Fe(NO3)3 and KSCN, while potassium nitrate is the compound that is formed as a result of the exchange of ions.
