Ocean Acidification

Ocean Acidification

decreasing pH of ocean waters due to absorption of excess atmospheric CO2 from the burning of fossil fuels

pH Scaled

the concentration of Hydrogen ions

Base

The concentration of [-OH] or Hydroxide Ions
>7 on pH Scale;
A solution or substance that decreases the hydrogen ion concentration in a solution.
Examples: Bleach, Ammonia, the ocean

Acid

The concentration of [H+] or Hydrogen Ions
<7 on pH Scale
A solution or substance that increase the hydrogen ion concentration of a solution.
Examples: Coffee, Acetic Acid (Vinegar), oranges,

Neutral pH

pH is equal to 7
contains equal numbers of hydrogen and hydroxide ions
[H+] = [-OH]
Example: WATER

Ion

A charged atom

Chemical Reaction

(chemistry) a process in which one or more substances are changed into others

Reactants

A starting material in a chemical reaction

Products

The elements or compounds produced by a chemical reaction.

Carbonic Acid

CO2 + H2O --> H2CO3

Calcification

process that hardens bones by adding calcium phosphate and collagen

Calcium Carbonate

CaCO3
spicules, mantle cavities, coral, teeth and insect's exoskeletons are made of this stuff
