How does adding carbon dioxide to the ocean affect its pH important to the world or soceity?

Answers

Increasing CO2 levels in the atmosphere are lead to a decrease in the oceans pH at CO2 combines with H2O to form Carbonic acid. Carbonic acid dissociates into H+ ions and HCO3- (bicarbonate). The H+ ions go on to combine with CO32- (carbonate ions) and decrease the concentration of these ions. Carbonate ions are required by many organisms for the formation of shells.

Ultimate impact is disruption of ocean ecosystems which can end up impacting society by negatively effecting our food supply chains and beyond that may have economic impacts.

, The number plane, or Cartesian plane, is divided into four quadrants by two perpendicular lines called the x-axis, a horizontal line, and the y-axis, a vertical line. These axes intersect at a point called the origin. Once a unit distance has been chosen, the position of any point in the plane can be uniquely represented by an ordered pair of numbers (x,y). For the point (5,3), for example, 5 is the x-coordinate and 3 is the y-coordinate, sometimes called the first and second coordinates.
