If 1.5g of salicylic acid is heated with an excess of acetic anhydride, what is the theoretical yield of acetylsalicyclic acid?
With 1,5 g of salicylic acid you can obtain theoretically 1,96 g aspirin (acetylsalicylic acid); but in the laboratory (or industry) I remember that the true yield of reaction is a little more than 90 %.
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 more polar methyl salicylate or salicylic acid?
salicylic acid (an acid) is more polar than methyl salicylate (an ester)
How does the structure of salicylic acid differ from that of benzoic acid?
Salicylic acid (C6H4(OH)COOH) has one more OH group than benzoic acid (C6H5COOH)
Why salicylate is more soluble than salicylic acid?
I assume you mean in water. Salicylate is a salt of salicylic acid. An organic salt is (pretty much) always more soluble in water than its non-salt counterpart. Water is polar, like dissolves like, etc.
Does ibroprophen contain aspirin?
No, it is a completely different chemical compound than aspirin, which is acetylsalicylic acid.
Why the solubility of salicylic acid in water change when sodium bicarbonate is added?
Salicylic acid is a benzene ring with two neighboring functional groups. One is a carboxylic acid (COOH) the other is a hydroxl (OH) When Bicarbonate(HCO3) is added to water with salicylic acid, the -HCO3 pulls the proton off of the hydroxyl making it a salicylate ion. Salicylate ion has a greater solubility than salicylic acid. I think. That's what 1 semester of Ochem will do for you.
Can salicylic acid be used on cats?
No it upsets the solfuric acid in the stomach [Q to answerer. Are you sure of sulfuric acid rather than hydrochloric?]
What pH would you expect aspirin dissolved in water to exhibit?
Aspirin is acetylsalicylic acid. From the name you should expect a pH of less than 7. Exactly how much less depends on how much aspirin and how much water.
Salicylic acid ointment what is it use for?
Salicylic acid cream is any type of cream or lotion that contains salicylic acid as an active ingredient. Salicylic acid is used for the treatment of skin conditions, most commonly acne, psoriasis, and warts. The percentage of salicylic acid found in the salicylic acid cream generally determines what the cream is used for. When applied to the skin, the salicylic acid will help to soften thickened skin and slough off dead skin cells; this will reveal new, fresher skin underneath and allow other medicines to better penetrate the skin. It also helps to prevent whiteheads and blackheads from forming. Salicylic acid cream is often used on the face as an acne treatment. It should be used regularly for it to work most effectively; the product will not work as well if it is simply applied to a blackhead or blemish after one already exists. The creams that contain salicylic acid tend to work best as a preventative measure for acne. Some people find they have a sensitivity to salicylic acid cream; in that case, an acne cream that contains benzoyl peroxide is another option. Both of these products are used regularly for the treatment of acne, and some people find that one will simply work better than the other.
What is the difference between extra strength aspirin and regular aspirin?
Extra strength aspirin has more active ingredients than regular strength aspirin. The active ingredient in aspirin is acetylsalicylic acid. The more of this, the more strength. Basically extra strength has more acetylsalicylic acid then regular aspirin.
Why acylation occur at phenol rather than carboxylic acid in salicylic acid?
This is actually quite simple: the pKa of the carboxylic acid group is only about 3, but the pKa of the phenolic group is 13.4.
