Q. Which of the following change/s is/are correct about “ocean acidification process”?
1.The concentration of hydrogen ions in the ocean increases.
2.The concentration of carbonate ions in the ocean increases.
3.The pH of the oceans increases.
How many of the statements given above are correct?
Answer: A
Notes:
Explanation: Ocean acidification is the change in ocean chemistry – lowering of ocean pH (i.e. increase in concentration of hydrogen ions) driven by the uptake of carbon compounds by the ocean from the atmosphere.
As the uptake of atmospheric carbon dioxide by the ocean increases, the concentration of hydrogen ions in the ocean increases, the concentration of carbonate ions decreases, the pH of the oceans decreases, and the oceans become less alkaline – this process is known as ocean acidification.
