Please do all parts of this problem. I will give the pointsquickly to the first person who answers all of the problems. Thankyou!
Considering the titration of 25.0 mL of 0.200 M methylamine,CH3NH2 with 0.200 M hydrochloric acid HCl,(use pKb = 3.38 for methylamine)
a. What volume(in mL) of 0.200M hydrochloric acid are required to "neutralize"25.0 mL of 0.200M methylamine?
b. What is thepH of the solution before anyacid is added?
c. What is thepH at the half-stoichiometric or half-equivalence point (that iswhat is the pH when you have added of the total volume of acid thatwould be required to react with all of the base originallypresent)?
d. What is thepH when 95% of the acid required to reach the stoichiometric pointhas been added?
e. What is thepH at the stoichiometric point?
f. What isthe pH when a 5% excess of the acid required to reach thestoichiometric point has been added?
