Sodium chloride conducts electricity when dissolved in water. what type of bond is present in Nacl?

Introduction:-

Today in this article I will explain you why sodium chloride conducts electricity when dissolved in water. and what type of bond is present in Nacl?

Explanation:-

To start this explanation I will tell you that Sodium Chloride (Nacl) is an ionic compound . Now question arise  that,

How Nacl is formed ?

Answer :-    

Na is a metal, the electronic configuration of sodium (Na) = 2,8, 1  to complete octet and become stable sodium needs to collect 7 electrons from other element to full fill its outer most shell i.e its third shell or 'M' shell to get its nearest noble gas Argon (2,8,8) and to full fil octet and become stable or Na has to give up its only valence shell electron (1) to get 2,8 electronic configuration of Neon as sodium is a metal so according to metals chemical property , all metals give up electrons they do not accept electrons or they are unable to accept electrons due to strong inter molecular force, thats why sodium is also unable to accept 7 electrons.

Again, chlorine (Cl) is a non metal and its electronic configuration is 2,8,7 so to fulfil its octet chlorine needs to accept one(1)electron or must have to give up its valence shell's 7 electrons  to get either its nearest noble 2,8,8(Argon) or 2,8 (Neon) gas configuration  to become stable due to non metals chemical property non metals never give up electrons, so chlorin is also unable to give up electrons.So in chemical reaction between sodium(Na) and chlorine ,Sodium (Na) gives up its lone valence electron to get its nearest noble gas Neon's configuration(2,8) and become stable in the mean time chlorine accepts the lone electron which is given up by sodium(Na) to get its nearest noble gas Argon's (2,8,8)configuration and become stable and by the process of electrons transfer they form ionic compound (Nacl)
The formation can be given by:-

Again in neutralisation reaction,

How can we form Sodium Chloride (Nacl)?

Answer:-

 In neutralisation reaction when Sodium hydroxide (NaoH) reacts with dilute hydrochloric acid they produce sodium chloride (Nacl) and water.
 The reaction can be given by :-
NaoH (aq) + Hcl (aq) —-->Nacl(aq) +H₂O 
At normal condition sodium chloride is electrically neutral as its positive charge (Na⁺) is balanced with negative charge(Cl⁻). But when Sodium chloride is dissolved in water sodium dissociates and liberates free ions so it conducts electricity.

The whole process can be given by :-

Ionisation of sodium chloride and water give:- Sodium chloride dissociates in Na⁺ and Cl⁻ ions; and water (H₂O) gives H⁺ and OH⁻ ions.

Ionisation Process:-

Nacl —----------> Na⁺ + Cl⁻ 
and
H₂O —-------> H⁺ + OH⁻
Now 

Since  NaOH(aq) and HCl (aq) is produced
so when sodium chloride (Nacl) is dissolved in water it conducts electricity as know generally aqueous solutions of sodium hydroxide (NaOH) and hydrochloric acid (Hcl) are good electrolytes, so they conduct electricity.

Conclusion:- 

Sodium Chloride is an ionic or electro valent compound and it has a high melting point and boiling point.As sodium chloride (Nacl) is formed by the electronic transfer of sodium ion (Na⁺) and chloride (Cl⁻) ion,

FREQUENTLY ASKED QUESTIONS:-

Name the ions present in sodium chloride(Nacl) salt.

Answer:- Sodium ion (Na⁺) and chloride ion (Cl⁻)

What type of bond is present in sodium chloride(Nacl)?

Answer:- Ionic bond.

What type of compound is sodium chloride(Nacl)?

Answer:- Ionic compound.

How an ionic compound is formed?

Answer:- An ionic compound is formed by the transfer of electrons from a metal atom to a non metal atom.

Why water(H₂O) is a good conductor of electricity?

Answer:- Water carries ions, so it is a polar solvent,by the dissociation of water it liberates hydrogen ion (H⁺) and hydroxyl ion( OH⁻) ions which conduct electricity easily, so water is a good conductor of electricity.
