Will a double replacement reaction takes place if a solution of sodium hydrogen carbonate is added to a solution of sodium chloride - No, a double replacement reaction did not take place.

In a double replacement reaction, two ionic compounds in solution that are dissociated into their constituent ions swap their cations (or their anions) to form two new ionic compounds, one of which is insoluble and forms a precipitate.

If no precipitate forms, then no reaction takes place since the ions have not been chemically changed.In order for two chemicals to react, there must be a mechanism.Both reactants sodium hydrogen carbonate and sodium chloride contain sodium ions, so a double replacement reaction is not possible.The Cl^-

ion is too weak a base to de-protonate the HCO3- ion, so there won’t be a significant acid-base reaction.None of the ions involved is a strong oxidizing or reducing agent, so we don’t expect a redox reaction to occur.There is no realistic mechanism in which NaCl and NaHCO3 will react with each other.

NaHCO3 + NaCl ------> x no reaction

Thus, in this case, there will be no double replacement reaction take place.

A double replacement reaction do not take place if a solution of sodium hydrogen carbonate is added to a solution of sodium chloride.

NO reaction occur.

Explanation:

Double replacement Reaction : A reaction in which positive and negative ions of two different compound exchange to form new compounds.

This is also called metathesis reaction.

For Example :

$Na_{2}SO_{4} + SrCl_{2}\rightarrow 2NaCl + SrSO_{4}$

Here Na+ and Sr2+ has exchanged

Cl- and SO4(2-) has exchanged their places.

So , Requirement of Double displacement reaction is :

Their should be salts of different cation and anion

$NaHCO_{3}$ = sodium hydrogen carbonate =Na+ cation

and HCO3 - anion

NaCl = Sodium Chloride = Na+ cation and Cl- anion

In both the reacts the cation is : Na+

So No-exchange of ions occur .

No- double displacement reaction.

The reality is , this reaction can't occur at all. It can neither be acid-base nor Redox Reaction

So ,

$NaCl + NaHCO_{3}\rightarrow No\ Reaction$
