Which of the following acids can be oxidized to form a stronger acid? H3PO4 HNO3 H2CO3 H3BO3 H2SO3 The answer is e, But why? can someone provide a detailed explanation to why HSO3- is somehow stronger than H2SO3? dont all polyprotic acid become weaker once it dissociates? (ka1 >ka2)??
Consider the reaction of HClO4 with P4O10 to form H3PO4 and Cl2O7. If 5.51 g P4O10 is reacted with excess HClO4 and 6.70 g of H3PO4 is ultimately isolated, what is the percent yield for the reaction?
Of the following, which has the weakest conjugate base? A. H3PO4 B. HCOOH C. HClO4 D. H2CO3
Which of the following statements is NOT true about acid anhydrides? A. Acid anhydrides are more reactive than esters but less reactive than acyl chlorides. B. An acid anhydride reacts with water to form an ester product. C. Acid anhydrides eliminate a carboxylate ion as a leaving group. D. An acid anhydride is considered to have a better leaving group (i.e. weaker base) than the leaving groups of esters, carboxylic acids, and amides. A B C D
will the following reaction occur as written? CH3NH2 он A) Yes, anhydrides can be converted into amides and carboxylic acids since the leaving group is a weaker base than CH3NH2. B) No, anhydrides cannot be converted into amides and carboxylic acids since the leaving group is a stronger base than CH3NH2. C) Yes, anhydrides can be converted into amides and carboxylic acids since the products have a greater amount of hydrogen-bonding. D) No, anhydrides cannot by converted into amides and...
List of Electrolytes: NaCl, H3PO4, HC2H3O2(also written as CH3COOH), H3BO3, C2H6O2, CaCl2, CH3OH, HCl, and AlCl3, Tap Water and DI Water 3. a) What can be concluded about how your acids are classified (are they strong, weak, or non-electrolytes?) b) Write a balanced equation for the dissociation of each of the acids, as was done for the ionic compounds. Here assume complete dissociation, disregarding the conductivity data for now. (HINT: Remember polyatomic ions! There should not be more than two...
Classify these compounds as strong acids or weak acids. HNO3,HBr,HCN,H2SO4,H3PO4
Which of the following substances form both ions and molecules in solution ? CH3OH Li2CO3 HClO4 Sr(OH)2 H3PO4
Give the oxidation number for each element in each of the following compounds. a) HClO4 b) Cd(OH)2 c) Sn(Cr2O7)2 d) Na2CO3 e) KBrO3
The reactivity sequence of carboxylic acid derivatives (acyl halides, anhydrides, acids, esters, amides) changes with the substituent. Acyl chlorides are most reactive, amides are least reactive. 1) Explain in detail why the reactivity changes in that sequence, 2) Where do carboxylates fit in that sequence and why? How does that impact on the way carboxylic acid reactions need to run? 3) Where do thioesters, RC(-O)SMe and acyl phosphates, RC(-O)OPO2OR fit in that sequence. Explain your decision The reactivity sequence of...
