What is a normal chloride level? What do acids and bases have in common? What is a buffer in chemistry? What is the structural formula of glutamic acid (pi = 3.2) at pH = 1? What ion does hydrogen form? How does the hydronium ion form?
The use of buffers is an important concept in acid-base chemistry. Here's a look at what buffers are and how they function. What Is a Buffer? There are two key terms associated with buffers. Abufferis anaqueous solutionthat has a highly stablepH. Abuffering agentis a weak acid or weak...
Good's buffers are excellent and widely used in a variety of biological experiments, but there are still problems. For example, The piperazine-based species (PIPES and HEPES) have a rather rich redox chemistry. In particular, Tris buffer is widely used, but it is not a Good's buffer[4]...

Unless it is a course limited to classical analysis, in which case I would probably choose inorganic, as it probably should give a wider and better understanding of the general chemistry concepts.
