Question

The hydrolysis of sodium carbonate involves the reaction between:
A.) Sodium ion and water
B.) $N{a^ + }$ And $O{H^ - }$
C.) $CO_3^{2 - }$ and water
D.) $CO_3^{2 - }$ and ${H^ + }$

Answer 1

Hint: In order to deal with this question first we will elaborate the term hydrolysis further we will do hydrolysis of sodium carbonate and we will write the reaction according to it we will find the required answer.

Complete step-by-step answer:

Hydrolysis is any chemical reaction in which one or more chemical bonds break up by a molecule of water. The term is commonly used for removal, reduction, and solving reactions in which the nucleophile is water.
Reactions of hydrolysis would be the opposite of a condensation reaction in which two molecules bind together into a larger one and expel a molecule of water. Hydrolysis thus requires water to break down, while condensation occurs by eliminating water and all other solvents. Any reactions to the hydration are hydrolysis.
Now we will write the reaction of hydrolysis of sodium carbonate:
\[
   \Rightarrow N{a_2}C{O_3} + 2{H_2}O \rightleftharpoons 2NaOH + {H_2}C{O_3} \\
   \Rightarrow 2Na + + CO_3^{2 - } + 2{H_2}O \rightleftharpoons 2N{a^ + } + 2O{H^ - } + {H_2}C{O_3} \\
   \Rightarrow CO_3^{2 - } + 2{H_2}O \rightleftharpoons + 2O{H^ - } + {H_2}C{O_3} \\
 \]
Hence, the hydrolysis of sodium carbonate involves the reaction between $CO_3^{2 - }$ and water.
So, the correct answer is option C.

Note- Hydrolysis reactions use water to break down polymers into monomers, which is the reverse of the synthesis of dehydration that shapes water when synthesizing a monomer polymer. Reactions to hydrolysis break bonds, and release steam. Salvation is an interaction between a solvent and a solvent which results in the solution stabilizing the solvent species. In the solved state, solvent molecules surround an ion in a solution to make it complex. Hydration is an important basic example of solvency, where the solution is water. In general, solvation is the law of like-attracts-like: Polar solvents such as sodium chloride are solved by polar solvents such as water.
