Write the general chemical equation (using an R group) showing the formation of a hydrogen ion from a carboxylic acid. Is this reaction reversible or irreversible? Are carboxylic acids weak or strong acids in general?
Which method is used for determining molecular mass of carboxylic acids?
Silver salt method is used for determining molecular mass of carboxylic acids. Carboxylic acids from insoluble salts which upon heating decompose to leave a residue of metallic silver, then this residue is filtered, dried and estimated. Was this answer helpful? A 0.607 g of a silver salt of a tribasic acid on combustion gave 0.37 g of Ag.
What is the formula for carboxylic acid?
The general formula of all Carboxylic Acids is C n H 2n+1 COOH. Where n = number of carbon atoms present in the molecule -1. The first five Carboxylic Acids are Methanoic Acid (HCOOH), Ethanoic Acid (CH 3 COOH), Propanoic Acid (CH 3 CH 2 COOH), Butanoic Acid (CH 3 CH 2 CH 2 COOH), and Pentanoic Acid (CH 3 CH 2 CH 2 CH 2 COOH). Q6.
Why are carboxylic acids acidic?
Answer: Carboxylic Acids are acidic because the hydrogen atom in the carboxylic acid group is directly attached to the highly electronegative oxygen atom. Due to this reason, the hydrogen atom can easily be lost in the solution leading to the formation of a hydrogen ion (H +) and a carboxylate anion (RCOO – ).

Key Information about Carboxylic Acids
Carboxylic acids are organic compounds characterized by the presence of a carboxyl group (-COOH). They are commonly found in various natural and synthetic substances and play essential roles in biological processes and industrial applications.
Examples of Carboxylic Acids
1. Acetic acid (CH3COOH) - Found in vinegar.
2. Citric acid (C6H8O7) - Found in citrus fruits like lemons and oranges.
3. Formic acid (HCOOH) - Found in ant stings and certain plants.
4. Butyric acid (CH3CH2CH2COOH) - Found in butter and dairy products.
5. Salicylic acid (C7H6O3) - Used in skincare products as an exfoliant.
Practice Exercises for Carboxylic Acids
- Write the structural formula for acetic acid.
- Identify the functional group present in citric acid.
- Name the carboxylic acid with the formula CH3CH2COOH.
- Draw the condensed structural formula for formic acid.
- List two uses of salicylic acid in everyday products.
Solutions:
- CH3COOH
- Carboxyl group (-COOH)
- Butyric acid
- HCOOH
- Skincare products (e.g., acne treatment, exfoliating creams)
Case Studies on Carboxylic Acids
1. The role of acetic acid in vinegar production and food preservation.
2. Citric acid's function as a flavor enhancer and preservative in food and beverage industry.
3. Formic acid's use in leather tanning and textile industry.
4. Butyric acid's importance in the fermentation process of dairy products.
5. Salicylic acid's application in pharmaceuticals for treating acne and skin conditions.
Subcategories in Carboxylic Acids
1. Aliphatic carboxylic acids: Straight-chain or branched carboxylic acids.
2. Aromatic carboxylic acids: Carboxylic acids containing an aromatic ring.
3. Hydroxy carboxylic acids: Carboxylic acids containing hydroxyl (-OH) group.
4. Dicarboxylic acids: Carboxylic acids with two carboxyl groups.
5. Unsaturated carboxylic acids: Carboxylic acids containing carbon-carbon double bonds.
These subcategories help classify and understand the structural diversity of carboxylic acids.
Important Notes on Carboxylic Acids
- Carboxylic acids are characterized by the carboxyl functional group (-COOH).
- They are weak acids that can donate a proton (H+) to form carboxylate ions.
- Many carboxylic acids have distinctive odors and flavors.
- They are widely used in food industry, pharmaceuticals, and chemical synthesis.
- Carboxylic acids participate in various chemical reactions including esterification, hydrolysis, and decarboxylation.
