How does the structure of salicylic acid differ from that of benzoic acid?
Salicylic acid has a hydroxyl group (-OH) attached to the benzene ring, while benzoic acid has a carboxylic acid group (-COOH) attached to the benzene ring. This difference results in salicylic acid being a phenol derivative and having different chemical properties compared to benzoic acid.
What is the dissociation constant for benzoic acid?
The dissociation constant (Ka) for benzoic acid is approximately 6.5 x 10^-5 at 25°C. This value indicates the extent to which benzoic acid dissociates into its conjugate base (benzoate ion) and a hydronium ion in solution. A higher Ka value indicates a stronger acid.
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.
What is the solubility of Benzoic acid in acetone?
Solubility of benzoic acid in acetone is 1.350 M
How do you extract benzoic acid from chloroform?
To extract benzoic acid from chloroform, first dissolve the benzoic acid in water. Then, add chloroform to the mixture and shake well to allow for the benzoic acid to transfer to the chloroform phase. Finally, separate the two phases and evaporate the chloroform to obtain the benzoic acid.

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
How do doctors treat athlete's foot?
Simple cases of athlete's foot usually respond to antifungal creams or sprays, such as tolnaftate (Aftate or Tinactin), clotrimazole, miconazole nitrate (Micatin products), or Whitfield's tincture made of salicylic acid and benzoic acid.
Is benzoic acid soluble in kerosene.?
Benzoic acid is soluble in kerosene.
What is the solubility of Benzoic acid in acetone?
Solubility of benzoic acid in acetone is 1.350 M
What does bluestar ointment contain?
Bluestar ointment contains ingredients such as camphor, menthol, eucalyptus oil, and salicylic acid. These ingredients work together to provide relief for various skin conditions such as itching, inflammation, and fungal infections.

Is Benzoic acid intensive or extensive?
Neither. Benzoic acid is... benzoic acid. Intensive and extensive are properties are characteristics of elements and compounds such as color, density, odor, conductivity, etc. To say benzoic acid is extensive or benzoic acid is intensive doesn't make sense.
What is the derivative of benzoic acid?
The derivative of benzoic acid is sodium benzoate, which is often used as a preservative in food and beverages due to its antimicrobial properties. Sodium benzoate is the sodium salt of benzoic acid and is more soluble in water than benzoic acid itself.
How do you prepare whitfield's ointment?
Preparation of Whitfield's Ointment. A monography describing Whitfield's Ointment can be found in the British Pharmacopoeia under the title: " Compound Benzoic Acid Ointment". It contains 6% benzoic acid and 3% salicylic acid in a suitable ointment base.
