Consider the titration of 25.0 mL of aqueous sample of methamphetamine (C10H14NH) with 0.0955M HCl. It took 21.25 mL of HCl to reach the equivalence point. Methamphetamine Kb = 1.0 x10^-10
a. Write the balanced net ionic equation for the titration reaction (including states)
b. calcuate the molar concentration of methamphetamine in the sample
c. calculate the initial pH of the methamphetamine sample
d. identify the predominant species that affects the pH at the equivalence point and calculate its molarity
e. calculate the pH at the equivalence point
f. calculate the pH after the addition of 10.0 mL of 0.0955 M HCl to the 25.0 mL sample of methamphetamine
