Which of the following concerning acid-base reactions is/are correct? Only strong acids and strong bases will undergo an acid-base reaction All acid-base reactions produce water and an ionic compound (salt); product. All reactions that form a gas are also acid-base reactions. 1 only 2 only 3 only 1, 2, and 3 none
Which of the following statements best explains the decreased acidic nature of carbonic acid compared to other carboxylic acids? OH carboxylic acid HO OH carbonic acid A. The extra hydroxyl group on the carbonic acid is an electron donating group, dampening the acidity of the molecule. B. The carbonyl group is an electron withdrawing group, increasing acidity of the OH through resonance. C. The carboxylate anion is stabilized by hyperconjugation and is a weak base, so the conjugate acid is...
Titration of a diprotic acid with a strong base You have a 10.0 mL solution containing 0.5 M carbonic acid. Carbonic acid is diprotic, with pKa1 = 6.35 and pKa2 = 10.33. You titrate this solution using 1.00 M NaOH . (a) Calculate the pH of the solution before adding any NaOH. (b) Calculate the amount of NaOH needed to reach the first midpoint. What is the pH? (c) Calculate the amount of NaOH needed to reach the first equivalence...

Using resonance and induction, explain why sulfuric and nitric acid are such strong acids. Also explain why sulfuric acid is a stronger acid than nitric acid (40 pts).
Typically, strong acids, like sulfuric acid, are used as an acid-catalyst for dehydration reactions of alcohols. What limitations/hazards does sulfuric acid pose in comparison to phosphoric acid? (select all that might apply) Extremely reactive Flammable Oxidizer Highly corrosive Odorous (smelly)
Solving for the pH in a mixture of acids is like dealing with a diprotic acid. You solve the problem by dealing with the acids in successive order. You start with the stronger acid (just like you start with the Ka1 because it is higher than the Ka2 for a diprotic). Afterward, you move on to the weaker acid. If a solution contains 0.014 M HCl and 0.100 M HF (Ka=6.6x10-4), what will be the pH of the solution?

You start with the stronger acid (just like you start with the Ka1 because it is higher than the Ka2 for a diprotic). Afterward, you move on to the weaker acid. If a solution contains 0.038 M HCl and 0.100 M HF (Ka=6.6x10-4), what will be the pH of the solution?
9. Sulfuric acid (H2S04), a diprotic acid, is a strong acid in its first deprotonation (deprotonation- loss of H'). The first deprotonation is considered complete (complete ionization). It is, however considered a weak acid for its second deprotonation with a Ka value of 1.2 X 102, For a 0.0456 M H2S04(aq) solution determine: (16 pts total) a. The chemical reaction equations for the successive loss of protons. (4 pts b. The concentration of HSO4-1 and H (H30') after the first...
