Reference no: EM13516883

Part A) A 116.8mL sample of 0.110M methylamine (CH3NH2, kB = 3.7*10^-4) is titrated with 0.255m HNO3 . Calculate the pH after the addition of each of the following volumes of acid.
a.) 0.0ml, 25.2mL, 50.4mL, and 75.6mL

Part B) Consider the titration of 55.0mL of 1.0M HCL with 1.0M NaOH . Find the pH at the following points.
Note: At the start of the titration the pH is 14.00, and at the equivamence point the pH is 7.00.

a.)After the addition of a large excess of the acid solution (in comparison with the acid volume needed to reach the equivalence point).

b.) Tell how many milliliters of acid are required to reach the equivalence point
