What are the Freezing-point depression constant of benzoic acid and salicylic acid?
The freezing-point depression constant (Kf) of benzoic acid is 6.22 °C/m, and for salicylic acid, it is 6.93 °C/m. These values indicate how much the freezing point of a solvent will decrease for each molal concentration of the solute.
Why Salysilic acid is stronger than benzoic acid?
In salicylic acid the hydrogen atom in OH group have a tendency to form hydrogen bonding with oxygen atom in the COO - group thus leaving the H+ ion freely available. In case of ortho methoxy benzoic acid, the possibility of hydrogen bonding is avoided by the presence of strong -CH3 group. Hence salicylic acid is stronger than ortho methoxy benzoic acid.
Which is more acidic formic acid or benzoic acid?
Formic acid is more acidic than benzoic acid. This is because formic acid has a simpler molecular structure with a hydrogen atom attached to a carboxyl group, making it easier to release the acidic hydrogen ion compared to benzoic acid, which has a more complex aromatic ring structure.
What is the chemical name of benzoic acid after heating?
The products of the thermal degradation of benzoic acid are carbon dioxide and water.
What is the relationship between salicylic acid and aspirin, and how do they differ in terms of their chemical composition and medicinal properties?
Salicylic acid is a precursor to aspirin, which is a derivative of salicylic acid. Aspirin is acetylsalicylic acid. They differ in their chemical composition as aspirin has an acetyl group attached to the salicylic acid molecule. In terms of medicinal properties, aspirin is commonly used as a pain reliever, anti-inflammatory, and fever reducer, while salicylic acid is often used in skincare products for its exfoliating properties.

Why benzoic acid and salicylic acid is added to milk and what is the basis for the test used to detect the presence of these acids?
Benzoic acid and salicylic acid are added to milk as preservatives to inhibit microbial growth and extend shelf life. To detect their presence, tests such as colorimetric assays or chromatography can be employed, which rely on the characteristic absorption spectra or specific reactions of these acids. For instance, benzoic acid can be detected using a reaction with bromine water that produces a color change, while salicylic acid can be identified through its ability to form a colored complex with iron(III) ions.

What is in the pepto-bismol drink?
Active Ingredient: Bismuth subsalicylate 262 mg (upset stomach reliever and antidiarrheal)Inactive Ingredients: benzoic acid, flavor, magnesium aluminum silicate, methylcellulose, red 22, red 28, saccharin sodium, salicylic acid, sodium salicylate, sorbic acid, water
Is benzoic acid an organic or inorganic compound?
The formula for benzoic acid is C7H6O2. As a rule, compounds that are cheifly variants of C, H, and O are organic, as is benzoic acid.
What is the framework structure of benzoic acid?
Benzoic acid has a simple aromatic structure consisting of a benzene ring (6 carbon atoms in a hexagonal ring) with a carboxylic acid functional group (COOH) attached at position 1.
Is benzoic acid soluble in kerosene.?
Benzoic acid is soluble in kerosene.
Does salicylic acid contain a benzene ring?
Yes, salicylic acid contains a benzene ring as part of its chemical structure. The benzene ring is connected to a carboxylic acid group through a hydroxyl group.
What is the solubility of Benzoic acid in acetone?
Solubility of benzoic acid in acetone is 1.350 M
