What will happen when you add sodium carbonate to the Easter which is synthesized by the reaction of a carboxylic acid and an alcohol catalysed by concentrated by sulphuric acid?
When sodium carbonate is added to the ester synthesized from a carboxylic acid and an alcohol, it will react with any unreacted carboxylic acid present, forming sodium salts and releasing carbon dioxide gas. This reaction will neutralize the acid, potentially leading to a decrease in acidity and altering the equilibrium of the esterification reaction. The addition of sodium carbonate may also lead to the formation of an emulsion or cloudiness in the mixture, depending on the specific conditions and concentrations involved.
What type of bonds present in the triglycerides are broken during the saponification reaction?
During the saponification reaction, the ester bonds in triglycerides are broken. Triglycerides consist of glycerol and three fatty acid chains linked by ester bonds. The saponification process involves the hydrolysis of these ester bonds in the presence of a strong base, typically sodium hydroxide or potassium hydroxide, resulting in the formation of glycerol and soap (the salt of fatty acids).
What does it mean to dry an organic liguid such as your crude ester?
Drying an organic liquid, such as a crude ester, involves removing any water or moisture that may be present in the solution. This is typically achieved by using drying agents, such as anhydrous salts (e.g., magnesium sulfate or sodium sulfate), which absorb the water. The goal is to achieve a pure product that is free of water, as the presence of moisture can interfere with subsequent reactions, affect product yield, or alter physical properties. Proper drying ensures that the organic liquid is suitable for further use or analysis.
What you combine to produce an ester?
An ester is produced by combining an alcohol and a carboxylic acid in a condensation reaction. This reaction results in the formation of an ester molecule and a molecule of water as a byproduct.
How can you obtained an acidic part of an ester?
An acidic part of an ester can be obtained by hydrolyzing the ester with an acid, such as hydrochloric acid or sulfuric acid. This reaction breaks the ester bond, yielding the parent carboxylic acid and alcohol.
Which of these is a carbonate?
Carbonate is a salt or ester of carbonic acid that contains the carbonate ion (CO3^2-). Examples of carbonates include calcium carbonate (CaCO3), sodium carbonate (Na2CO3), and potassium carbonate (K2CO3).
Why you add sodium carbonate to the mixture during preparation of ester?
Sodium carbonate is added during the preparation of esters to neutralize the acidic byproduct formed during the reaction. This helps to facilitate the esterification reaction and improve the yield of the desired ester product.

What is the purpose of adding sodium carbonate in esterification?
Sodium carbonate is added in esterification reactions to act as a catalyst for the reaction. It helps to speed up the esterification process and increase the yield of the desired ester product. Additionally, it helps to neutralize any acidic byproducts generated during the reaction.
Test for ester?
Acid hydrolysis using sulphuric acid and water (equilibrium reaction). The ester splits into a carboxylic acid and alcohol, protons donated from the acid. The solution can then be distilled and the remaining acid can be checked using UV indicator. Acid hydrolysis using sulphuric acid and water (equilibrium reaction).

What is inside of glow sticks?
Glow sticks contain a mixture of chemicals that includes hydrogen peroxide, a fluorescent dye, and a phenyl oxalate ester. When these chemicals are mixed by bending the stick, a chemical reaction occurs that produces light through chemiluminescence.
Reaction between methyl salicylate and sodium hydroxide?
When methyl salicylate (oil of wintergreen) reacts with sodium hydroxide (NaOH), it undergoes saponification to form sodium salicylate and methanol. This reaction is a base-catalyzed ester hydrolysis reaction that converts the ester functional group of methyl salicylate into a carboxylate salt.
What is inside glowy sticks?

What is the name of solution can dissolve ester?
Which ester specifically? Some of them are soluble in water; acetone is also a pretty good solvent for many esters.
What is the formula for hydrogen carbonate ion?
CO32-.
What is alendronate?
An alendronate is a salt or ester of alendronic acid, or the derived sodium content used to treat osteoporosis.
