Question
Potassium (at No.19) and chlorine (at No.17) react to form a compound. Explain the formation of the compound on the basis of reducing agent.
Solution
\[\ce{2K + Cl2 -> 2KCl}\]
A reducing agent reduces other substances either by providing electrons, hydrogen, or an electropositive ion or by removing oxygen or an electronegative ion.
\[\ce{K -> K+ + e-}\]
