Click For Summary
A buffer solution is defined as a system that resists changes in pH when small amounts of acid or base are added, typically containing a weak acid and its conjugate base or a weak base and its conjugate acid. The discussion revolves around identifying pairs of solutions that can form a buffer when mixed in equal volumes. The suitable pairs include weak acids with their corresponding strong bases, such as acetic acid (HC2H3O2) with sodium hydroxide (NaOH) or ammonia (NH3) with hydrochloric acid (HCl). Participants clarify that this topic is relevant to Chemistry II and is included in the ACS exam, emphasizing the importance of understanding buffer solutions in this context. Understanding buffer solutions is crucial for solving related problems in chemistry courses.

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.
