Titration Problem

kolip0678877 — 2025-07-26 02:18:23 UTC

A student titrates 35.0 mL of 0.200 M methylamine (CH₃NH₂), a weak base (Kb = 4.4 × 10⁻⁴), with 0.100 M hydrochloric acid (HCl), a strong acid. After the student adds 10.0 mL of 0.100 M HCl to the base solution, calculate the pH of the solution. Determine the pH at the equivalence point, where just enough HCl has been added to fully neutralize the methylamine. If the student continues adding HCl and reaches a total of 80.0 mL of 0.100 M HCl added, calculate the pH of the resulting solution.

Identify what you're being given and asked

The problem is asking you to find ph at certain stages. First is buffer, then at equivalence, and lastly excess. You're also given volumes of the solution, concentrations, and kb. This will come in handy.

Before you jump in, be prepared

Being prepared is essential, just jumping into the problem could prove a fatal mistake

First Section: Buffer

kolip0678877 — 2025-07-26 03:55:45 UTC

So far, so good

Second Section: At Equivalence

kolip0678877 — 2025-07-26 03:57:37 UTC

You're almost done!!

kolip0678877 — 2025-07-26 03:59:02 UTC

Last Section: Excess

Was that really so hard ?

Last advice

Practicing titration problems will build up your confidence and engrave the concepts into your mind. You'll will no longer fear titration problems but look forward to aceing them!!
