me in words rather than structures?
1. The name acetic anhydride implies that the compound will react with water to form acetic acid. Write the equation for the reaction. - (CH3CO)20 + H20 → 2CH3COOH - Or CH3COOCOCH3 + H2O → 2CH3COOH 2. Propose a mechanism for this reaction (salicylic acid with acetic anhydride). Identify the nucleophile and the electrophile.

I really appreciate if someone can tell me how I can know the major and minor species for the tritations of strong base- strong acid, strong acid- strong base and weak acid- strong base. I am looking for the major and minor species at the point before any addition of titrant, before the equivalence point, at equivalece point and after equivalence point. Could you please give a detailed explanation with the chemical equations. Thanks

QUESTION 3 Salicylic acid reacts with acetic anhydride to form aspirin and acetic acid as shown. Use the equation to answer Questions 3 – 6. (salicylic acid) (aspirin) C7H6O3 (s) + C4H6O3 (l) → C9H8O4 (s) + CH3COOH (l) MM = 138 MM = 180 If we divide 180 by 138 we find that 1.00 g salicylic acid will produce a maximum of 1.30 g aspirin. 3. A student starts with 3.20 g salicylic acid. What is the maximum amount...
