Question

a) Given 20.00 mL of 0.2000 M diethylamine (CH₃CH₂)₂NH (K_b = 3.1 x 10^-4), determine the pH for the titration against 0.1000 M Hal at the following HCl volumes: i) 0.0 mL, ii) 1/4 eq pt, iii) 15.00 mL, iv) 20.00 mL, v) 3/4 eq pt, vi) 35.00 mL, vii) at the eq pt, viii) 50.00 mL, ix) 20.00 mL beyond the eq point.

b) Use the results of part 'a' to sketch the titration curve. Make the line as smooth as possible.
