chapter 6 fill in the blank

the pH of seawater is generally between blank

7.5 and 8.5

sodium and chloride ions account for BLANK of the salt ions present in seawater

86 percent

oceanographers measure seawaters salt content or Blank in grams of salt per kilogram of seawater

Salinity

blank are sedimentary deposits of salt left behind after a portion of the sea has undergone tremendous evaporation

evapories

the most important process for the removal of elements from seawater is the blank of ions into fine sedimentary particles

adsorption

non oxygen using bacteria are called blank

anaerobic

water is termed blank when it has been stripped of dissolved oxygen

anoxic

carbon dioxide acts as a blank to control pH in the ocean

buffer

blank is defined as the quantity of silver required to remove all the halogens from .3285 kilograms

chlorinity

the major constituents of open ocean seawater do not change their ratios with respect to one another have termed blank

conservative

the sources of the salts in the worlds ocean are the blank of the earth

crust and interior

blank is the process of obtaining fresh water from salt water

desalination

when salts are added to water the salt

dissolves

ions required for plant growth are known as blank

nutrients

blank is the movement of water across a semipermeable membrane

osmosis

the blank between the amounts of major ions in open ocean water are constant

ratios

the average time that an ion remains in solution in seawater is called blank

residence time

the amount of gas that can be held in solution without causing the solution to either gain or lose gas is called the blank

saturation value

when the concentrations of a substance in water is greater than the saturation level for that substance it is said to be blank

supersaturated

blank are elements present in seawater at concentrations less than 1 ppm

trace elements
