Question

Is this reaction a double displacement reaction?
$C{{H}_{3}}COOH\text{ }\left( aq \right)\text{ }+\text{ }NaHC{{O}_{3}}~\left( s \right)\text{ }\to \text{ }C{{H}_{3}}COONa\text{ }\left( aq \right)\text{ }+\text{ }C{{O}_{2}}~\left( g \right)\text{ }+\text{ }{{H}_{2}}O\text{ }\left( l \right)$

Answer 1

A chemical reaction is a process that results in the chemical change of one set of chemical substances into another set of chemical substances. Chemical reactions are often defined as changes in the locations of electrons in the formation and breaking of chemical bonds between atoms, with no change in the nuclei (no change in the elements present), and may be represented using a chemical equation.

Complete answer:
A salt metathesis reaction, also known as a double replacement reaction, is a chemical reaction in which two chemical species swap bonds, resulting in the formation of products having comparable or equal bonding affiliations. The overall scheme represents this response $A-B\text{ }+\text{ }C-D\text{ }\to \text{ }A-D\text{ }+\text{ }C-B$
Ionic or covalent bonds might form between the reacting species. These reactions usually culminate in the precipitation of a single product.
When at least one of the compounds does not dissolve in the solvent and the ligand or ion exchange occurs in the solid form of the reactant, the term double decomposition is employed. Consider the following scenario: $AX\left( aq \right)\text{ }+\text{ }BY\left( s \right)\text{ }\to \text{ }AY\left( aq \right)\text{ }+\text{ }BX\left( s \right)$
Sodium hydrogen carbonate, commonly known as sodium bicarbonate, interacts with acetic acid to form sodium acetate, which produces carbon dioxide gas, which is proven when lime water turns milky. This is a carboxylic acid confirmatory test.
$CHCOOH\left( aq \right)\text{ }+\text{ }NaHCO\left( s \right)\text{ }\to \text{ }CHCOONa\text{ }+\text{ }HCO\left( aq \right)$
Because the Na is displaced by the H of CH3COOH, this is a twofold displacement reaction. Because one component is transformed into two distinct compounds, there is also a breakdown process.
$HCO\left( aq \right)\text{ }\to \text{ }CO\left( g \right)\text{ }+\text{ }HO\left( l \right)$
Because one substance is transformed into two distinct compounds, this is a breakdown process.
The first half of the reaction is double displacement in nature.
Additional Information:
As a result, one-half of this reaction is a twofold displacement reaction.

Note:
The chemical compound sodium bicarbonate has the formula $\mathbf{NaHC}{{\mathbf{O}}_{\mathbf{3}}}$ . A sodium cation ( $N{{a}^{+}}$ ) and a bicarbonate anion ( $HC{{O}_{3}}^{-}$ ) make up this salt. Sodium bicarbonate is a crystalline white substance that frequently appears as a fine powder. It tastes somewhat salty and alkaline, similar to washing soda (sodium carbonate). Nahcolite is the natural mineral form. It is found dissolved in many mineral springs as a component of the mineral natron.
