Exam 5: Seawater

The oceans are a major contributor of oxygen to the earth's atmosphere.

The rule of constancy of composition of sea salts for open-ocean water specifies that regardless of the salinity, the major ions always appear in the same ratio to each other. 

The salinity of a water sample can be determined by multiplying its ________ by 1.80655.

More oxygen is found in surface waters at lower latitudes than in surface waters at polar latitudes.

Carbon dioxide in seawater keeps the water's pH

The pH of seawater is regulated by

Electrical conductivity readings at a known temperature measure

When the salinity of a seawater sample changes, the ratio of the major salt ions does not change.

Sources of the oceans' salts are believed to include

Nutrients and dissolved gases in seawater are considered conservative substances.

If the salinity of ocean water is 36‰, there are ______g of salt left from evaporating 2kg of seawater.

The process of adherence of ions and molecules onto a particle's surface is called _______.

Sea surface salinity is a function of _________ and __________.

An ion with a positive charge is known as a cation.

Check each of the following constitutents of seawater that are conservative constituents.

The proportions of the major salts in seawater are constantly changing.

Carbon dioxide is added to seawater by

The depth at which the rate of photosynthesis balances the rate of plant respiration is known as the

Sources of oxygen in the open sea include

Electrodialysis produces ________ from low-salinity seawater.
