Question:
- Sodium chloride, written as NaCl, is what we commonly refer toas table salt. How is a salt defined as it relates to chemistry?What other types of salts exists? Give a few examples.
From the graph on Page 1 in the Seawater Chemistry document, thetemperature (ºC) increases nears the equator and decreases towardsthe poles. - Give an explanation why the density (g/cm3) is higher at thepoles than it is at the equator.
- Discuss why there two salinity (ppt) peaks near each of theTropics.
- List the name and chemical formula of the two (2) majordissolved ions in ocean water.
- What are the primary sources of these two dissolved ions?
- How is chlorinity related to salinity? When would you use onemeasurement over the other?
- What is the constant ratio of salinity to chlorideconcentration? Explain why this is a constant.
- Describe one of the main methods used to measure salinity. Issalinity measured directly or is it indirectly calculated? In yourown words, explain the process you'd use to measure the pH of anunknown solution.
- A large chunk of ice breaks off from a massive glacier inAntarctic. What happens to the pH of the water surrounding the iceas it melts?
- Would the salinity of a large brackish water bay substantiallyincrease, decrease, or experience negligible change after a heavyrain storm? Explain your reasoning.
