PPT-Ch. 3: Chemical and Physical Features of Seawater and the

World Ocean 31 The Waters of the Ocean A The Unique Nature of Pure Water All matter is made of atoms Elements are make from one kind of atom A molecule is two or more different atoms combined. CS Mexico INTRODUCTION INTRODUCTION About 75 of Earth s surface is water of this quantity Saltwater oceans hold 9725 of surface water and only 3 is fresh water but only 07 it is available for human use from rives streams lakes ground water etc The o First lecture:. 1.

Activities ≠ concentrations. Activities are “effective” concentrations. Interactions between ions and solutes that change chemical potential from standard state. Cause “non-ideal” behavior of the ions in solution. S8P1d. Distinguish between physical and chemical properties of matter as physical (i.e., density, melting point, boiling point) or chemical (i.e., reactivity, combustibility) How are physical and chemical properties different? Ocean Acidification The Fundamental Chemistry Behind This Phenomenon Objectives Learning Goals Understand how atmospheric CO 2 affects seawater pH Explain the seawater carbonate chemistry reaction(s) Daniel Winkler.
