Abstract
This paper explains the buffer systems in the human body. It specifically focuses on the role of the buffer systems in maintaining proper body pH. The paper explains the effect on the bodily systems if changes occur to shift the balance of acid-base systems to a range that is out of the norm. The paper looks at various cations and ions in the body and their function.

From the Paper
"Buffers and buffer reactions are one of the most important reactions in the human body. The body has a limited tolerance for changes in pH. The ability to maintain proper pH can present as a primary cause of concern, or it can represent a secondary complication. The most common problem associated with pH shifts are heart arrythmias and pulmonary problems. The six chemicals discussed in this research are the most important ones for maintenance of proper pH. However, there are many others that play a minor role. Understanding how the body maintains homeostasis is one of the most important concepts that any medical professional can know."

Abstract
This paper describes four different chemistry experiments: (1) titration of acids and bases; (2) hydrolysis of salts; (3) relative strengths of acids; and (4) reactions of anions and cations. The paper gives the chemical formulas for the reactions and answers questions at the end of each experiment.

Abstract
After a brief historical introduction to lead compounds, it explains what +2 and +4 cations are and examines their uses. The physical and chemical properties of the lead (II) halides are also discussed, with mention of "mixed" halides (e.g., PbFCl).

From the Paper
"Lead, located at the bottom of group IVA on the periodic table is well known for being a massive (atomic mass is 207.2 amu) and dense element. The density characteristics associated with lead arise from its rather compact structure despite its large size. This occurs in accordance to the periodic trend that atom size decreases as one moves left to right across a period. This trend, in conjunction with the massive properties found among the period six elements, accounts for the elements ranging from osmium to lead in that row being the densest (osmium does have the largest density) known to exist."
