Discussion Overview

The discussion revolves around identifying which pair of solutions forms a buffer solution when mixed in equal volumes. Participants explore various combinations of acids and bases, as well as the definition and requirements of buffer solutions.

Discussion Character

  • Homework-related
  • Conceptual clarification

Main Points Raised

  • One participant lists four pairs of solutions and asks which forms a buffer solution.
  • Another participant inquires about the definition of a buffer solution and what it must contain.
  • There is a mention of the context of the problem being related to a Chemistry II course and the ACS exam.
  • Some participants discuss the structure of the ACS exam and its relation to the content covered in Chemistry courses.

Areas of Agreement / Disagreement

Participants express uncertainty regarding the definition of a buffer solution and its requirements, indicating that there is no consensus on the best pair of solutions for forming a buffer.

Contextual Notes

Some participants appear to lack familiarity with the concept of buffer solutions, which may affect their ability to engage with the problem effectively.

Which pair of solutions forms a buffer solution when equal volumes of each are mixed?

a. 0.20 M HCl and .20 M NaOH
b. 0.40 M HC2H3O2 and 0.20 M NaOH
c. 0.20 M HCl and 0.20 M NH3
d. 0.40 M HCl and 0.20 M NH3

Thanks

Is this Chem II? because I don't know "buffer solution". This problem is in ACS.
 
Yes this is Chem II. There are 2 version of the ACS exam. One is for first semester (chem I) and the gen chem exam is for chem I and II. Was your course I or II? We did a big long chapter on buffers in chem II.

Yes, its inorganic II. If you bought the ACS review book, it'll contain both inorganic I & II. But you won't see questions like this on the inorganic I exam.
