Calculate the pH at the equivalence point for the titration of 0.150 M methylamine (CH3NH2) with 0.150 M HCl. The Kb of methylamine is 5.0× 10–4.
Calculate the pH at the equivalence point in the titration of 60.0 mL of 0.140 M methylamine (Kb = 4.4 × 10−4) with 0.270 M HCl.
Calculate the pH at the equivalence point in the titration of 50 mL of 0.19 M methylamine (Kb = 4.3 ×10−4) with a 0.38 M HCl solution.
QUESTION 12 Determine the volume in mL of 0.25 M HCl(aq) needed to reach the equivalence (stoichiometric) point in the titration of 47.3 mL of 0.29 M (CH3)3(aqXaq). The Kb of trimethylamine is 6.5 x 10-5. Enter your answer with two decimal places and no units.
CALCULATE THE PH AT THE EQUIVALENCE POINT FOR THE TITRATION OF 0.250M METHYLAMINE (CH3NH2) WITH 0.25 HCL. THE Kb OF METHYLAMINE IS 5.0X10-4. (HINT: THERE IS NO VALUE FOR VOLUME IN THE PROBLEM SO I AM NOT SURE HOW TO PROCEED! PLEASE HELP.)
Thank you in advance. A titration of 50 ml of 0.20 M methyl amine, CH3NH2, required 50 ml of 0.20 M HCL to reach the equivalence point. what is the pH at this endpoint? Kb for CH3NH2 = 4 x 10^-4
