Question

What compound is formed when the soft putty-like metal sodium (Na) reacts with the green-colored poisonous gas chlorine (C12)?

Answer 1

Answer:

              Option-B (Table Salt) is the correct answer.

Explanation:

                     Salt formation takes place when Metal (like Na) and Non-metals (like Cl₂) are reacted. In given statement the reaction will be as follow:

                                        2 Na + Cl₂   →   2 NaCl

Above reaction can be divided as;

Oxidation Reaction:

The Sodium Atom (Na) being metal loses its single valence electron to attain a stable noble gas configuration as,

                                           Na  →  Na⁺  +  1 e⁻

Reduction Reaction:

The Chlorine Atom being non-metals accepts the electron from Na atom and changes into Chloride ion as,

                                          Cl₂  +  2 e⁻   →    2 Cl⁻

Formation of Salt:

Hence, the Na⁺ and Cl⁻ formed attracts each other and form an Ionic bond as,

                                            Na⁺  +  Cl⁻    →     NaCl

Note: You should remember that NaCl (Sodium Chloride) is also known as Table Salt :)
