Concept introduction:
In a proton transfer reaction, a proton is transferred from a Bronsted–Lowry acid (proton donor) to a Bronsted–Lowry base (proton acceptor) in a single elementary step in which one bond is broken and another is formed simultaneously. The conjugate acid is the species that the base becomes after gaining a proton, and the conjugate base is the species that the acid becomes after losing a proton. The curved arrow notation shows the movement of valence electrons, not atoms. Each double-barbed curved arrow shows the movement of two valence electrons. To represent bond breaking, the tail of the arrow originates from the center of a bond whereas to represent bond formation, the head of arrow points to an atom which forms the new bond, that is,

- What are the major species in solution after NaHSO4 is dissolved in water? What happens to the pH of the solution as more NaHSO4 is added? Why? Would the results vary if baking soda (NaHCO3) were used instead?arrow_forwardWhy is H3O+ the strongest acid and OH the strongest base that can exist in significant amounts in aqueous solutions?arrow_forwardThe formula for tartaric acid is preferably written as H2C4H4O6 rather than as C4H6O6. Explain why.arrow_forward
- For an acid-base reaction, what is the reacting species (the ion or molecule that appears in the chemical equation) in the following bases? (a) barium hydroxide (b) trimethylamine (CH3)3N (c) aniline, C6H5NH2 (d) sodium hydroxidearrow_forwardHydrogen, H2S, and sodium acetate, NaCH3CO2 are mixed in water. Using Table 16.2, write a balanced equation for the acid-base reaction that could in principle, occur. Does the equilibrium lie toward the products or the reactants?arrow_forwardThe weak base methylamine, CH3NH2, has Kb=4.2104. It reacts with water according to the equation. CH3NH2(aq)+H2O(l)CH3NH3+(aq)+OH(aq) Calculate the equilibrium hydroxide ion concentration in a 0.25 M solution of the base. What are the pH and pOH of the solution?arrow_forward
- Write two BrnstedLowry acid-base reactions and show how they represent proton-transfer reactions.arrow_forward. Calculate the pH corresponding to each of the pOH values listed, and indicate whether each solution is acidic, basic, or neutral. a. pOH = 4.32 b. pOH = 8.90 c. pOH = 1.81 d. pOH = 13.1arrow_forward
