Hi everyone I am new to the forum! If I do this wrong please let me know. I need help with this particular discussion board. Water is ubiquitous and necessary for life on our planet. Describe the numerous unique properties of water and how it supports life. With specific applications to humans, what are the most common chemical contaminants of municipal water supplies in the country in which you reside? Why? What properties do these chemicals possess that allows them to be easy contaminants, and what risk do they pose to humans? Is access to clean drinking water a basic human right, do you think? Or is it merely a luxury? Why or why not?
2.) How do soaps work? Describe their chemical properties and give an example (including chemical formula) of a particular soap.
3.)Chlorine gas (Cl2; the 2 here is a subscript) is a gas at room temperature that can kill you if inhaled. When chlorine atoms bonds to other atoms, however, the resulting compounds have their own and completely different/unique properties and uses.
A) For example, table salt contains chlorine atoms, yet it doesn’t kill us if we consume it (well, at least in moderation!). Describe the chemical properties of table salt (NaCl). As you construct your response, try putting some table salt in a cup of water, and then try putting some into a cup of vegetable or cooking oil. Stir them both. What's the difference in terms of what you notice? How does this demonstrate the properties you explain?
B) By mixing chlorine gas with sodium hydroxide (NaOH), a.k.a. lye, you create sodium hypochlorite (NaOCl). NaOCl mixed with water is your common household bleach. Bleach is usually used as a disinfectant. Why? BE SPECIFIC HERE.
