SOLVED: Consider the titration of 50.0 mL of 0.0500 M C6H5NH2 (a weak base; Kb = 4.30e-10) with 0.100 M HBr. Calculate the pH after the following volumes of titrant have been added:(a) 0.0 mLpH = (b) 6.3 mLpH = (c) 12.5 mLpH = (d) 18.8 mLpH = (e) 25.0 mLpH = (f) 47.5 mLpH =

SOLVED:Write ionization equations and base ionization constant expressions for the following bases. a. hexylamine (C6 H13 NH2) b. propylamine (C3 H7 NH2) c. carbonate ion (CO3^2-) d. hydrogen sulfite ion (HSO3^-)

Write a formula for the conjugate acid formed when each of the following behaves as a Bronsted base: a. NH2 ^- b. CO3 ^2- c. OH^- d. (CH3)2 NH e. NO2^- | Numerade

21. 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)3 N (c) aniline, C6 H5 NH2 (d) sodium hydroxide | Numerade

4-Nitroaniline is a weaker base compared to 4 -cyanoaniline. This is because (a) both nitro and cyano are strong electron withdrawing groups. (b) the lone pair of nitrogen of the NH2 group is delocalised in 4 -nitro aniline and not in 4 -cyanoaniline. (c) the negative charge resides on the more electronegative oxygen in nitro aniline in the resonance delocalization. (d) cyano group is aligned planar with the ring. | Numerade

Consider the base hydroxylamine, NH2 OH. (a) What is the conjugate acid of hydroxylamine? (b) When it acts as a base, which atom in hydroxylamine accepts a proton? (c) There are two atoms in hydroxylamine that have nonbonding electron pairs that could act as proton acceptors. Use Lewis structures and formal charges ∞∞(Section 8.5) to rationalize why one of these two atoms is a much better proton acceptor than the other. | Numerade

SOLVED: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)3 N (c) aniline, C6 H5 NH2 (d) sodium hydroxide
