Potassium chloride and fluorine undergo a single replacement reaction. predict the formula of the two products of the reaction.

The formula of the products are :

KF = Potassium fluoride

Cl2 = Chlorine

Explanation:

Single replacement reaction :

It is the reaction in which one element(More reactive) replace other element (less reactive) in the compound . These are represented by :

Here , the more Reactive A replaces the less reactive B from its compound BC.

Note , that A and B should be almost similar in properties.

Now ,  Chlorine and Fluorine are both Non - metals whereas Potassium is metal . So Potassium is not replaced in the reaction , since it is metal and only metal can replace other metals.

Chlorine is replaced by Fluorine in this reaction because The reactivity of F is greater than Cl.

The balanced equation is :

The reactants are :

KCl = Potassium Chloride

F2 = Fluorine

The formula of the products are :

KF = Potassium fluoride

Cl2 = Chlorine gas
