What is ocean acidification, what is the primary cause of it, and what effect does it have on marine organisms.
Homework Answers
Ocean acidification refers to reduction in pH of oceans due to absorption of carbon dioxide from atmosphere. Normal pH of sea water is slightly basic.
Atmospheric pollution is the main cause of ocean acidification. Carbon dioxide is released into atmosphere by man made activities like from burning of fuels, combustion and from industries.
Oceans need an optimal pH for maintenance of normal healthy ecosystem. The shells and skeleton of marine organisms are made up of calcium carbonate. Ocean acidification leads to depletion of this mineral, reducing the ability of organisms to produce shells. Acidification reduces the metabolic rate, immune responses of organisms. It also causes coral bleaching.

Explain how the buffer system in our blood is related to ocean acidification. According to the video “Changing Waters on the Oregon Coast”: Q1: What aquatic organisms are most vulnerable to ocean acidification? Q2: Why will the Oregon coast continue to see an increase in ocean acidification for 30-35 years even if we were to completely stop CO2 emissions today and cap the atmospheric levels?

8. Many marine organisms generate shells from calcium carbonate (CaCO3). A. (4 pts) Write out the balanced chemical equation that corresponds to dissociation of calcium carbonate. B. (5 pts) One of the many consequences of climate change is ocean acidification, which occurs because rising surface temperatures allow more CO2 to dissolve in the water, resulting in increased H3O* concentration in the ocean. Using a chemical reaction and a...
6. Between 1751 and 1994, the pH of the ocean changed from 8.25 to 8.14. By 2100, the pH of the ocean is expected to be between 7.64-7.84. Is this an increase or decrease in pH? Does that correspond...
