Weak Acid - Strong Base titration. Too little information?

Click For Summary

Discussion Overview

The discussion revolves around a chemistry homework problem involving the titration of a weak acid (acetic acid) with a strong base (sodium hydroxide). The participant seeks assistance with calculations related to the concentration of the acid, specifically using the Henderson-Hasselbalch equation and other relevant concepts.

Discussion Character

  • Homework-related
  • Mathematical reasoning

Main Points Raised

  • The participant outlines the details of the titration, including the concentrations and volumes of the acid and base.
  • Some participants suggest resources, such as video lectures on titration and the Henderson-Hasselbalch equation, to aid in understanding the topic.
  • Another participant points to a website that provides titration calculation guidance, implying that the problem may be straightforward.

Areas of Agreement / Disagreement

There is no explicit consensus on the approach to solving the problem, as the original poster expresses uncertainty about how to begin, while others provide resources without directly addressing the calculations.

Contextual Notes

The original poster's understanding of the necessary equations and concepts appears limited, and there may be assumptions about prior knowledge that are not explicitly stated.

Homework Statement


In order to achieve a high result in this chemistry assignment, I need to have demonstrated a knowledge of challenging content not discussed in class. Every other part of this assignment I've covered (Intro, method, discussion etc), I am just stuck with the calculations.

This is what I know:
Base: Sodium Hydroxide
Acid: Acetic Acid
Concentration of Base: 1.06M
pH of solution: 7
Volume of Base: 20mL
Volume of Acid: 26mL
pKa of Acid: 4.75

What I need to find out:
Concentration of Acid.

Homework Equations


Henderson Hasselbalch Equation ?
Not really sure what else is needed.

The Attempt at a Solution


Not even the slightest clue as to where to begin.
 
Physics news on Phys.org
If you say the content was not covered in class, then you may find this a useful resource. (Since you said you need to demonstrate a knowledge not simple "answer this one question"). This link has a series of short video lectures covering tritation and such.

http://www.khanacademy.org/?video=titration-roundup#chemistry

In the center column, you will see the Acid/Base lecture where it starts, but you might want to begin with the Buffers and Hendersen Hasselbalch video.
 
Thank you that looks to be a great resource.
