Question

Two 25.0 mL samples, one 0.200 MKOH and the other 0.200 M CH3NH2, were titrated with 0.100 MHI. Answer each of the following questions regarding these two titrations.

A.) What is the volume of added acid at the equivalence point for KOH?

B.) What is the volume of added acid at the equivalence point for CH3NH2?

C.) Predict whether the pH at the equivalence point for each titration will be acidic, basic, or neutral.

neutral for KOH and basic for CH3NH2

neutral for KOH and acidic for CH3NH2

basic for KOH and neutral for CH3NH2

acidic for KOH and neutral for CH3NH2

neutral for both

D.)

Predict which titration curve will have the lowest initial pH.

The initial pH will be lower for KOH.

The initial pH will be lower for CH3NH2.
