Evaluate the article
(Compose a detailed evaluation of the article here, considering each of the key aspects listed above. Consider the guiding questions, and check out the examples of what a useful Wikipedia article evaluation looks like.)


 * 1) Lead Section: too long to serve as a good wiki link from other articles; contains details that are poorly defined or confusing.
 * 2) Content: mostly good, but contains errors and misleading sections, especially about calculating pH of a buffer solution. Could use a link to Good's buffers instead of a separate list;
 * 3) Tone and Balance: no issues.
 * 4) Sources and References: most of the citations are OK, but there are many more appropriate sources for a topic of this importance.
 * 5) Organization and writing quality: needs improvement. Much of the text is opaque to non-experts.
 * 6) Images and media: Aside from some molecular structures, there is only one graph. Needs more to enhance understanding of the text.
 * 7) Overall impressions:
 * 8) This is an article of high importance and should be improved.
 * 9) The most glaring deficiency is in the section called 'Calculating Buffer pH', which should be completely rewritten using the Henderson-Hasselbalch equation and exact mathematical approaches.
