Question

Quizplus · Accepted Answer

The burning of fossil fuels, such as coal, oil, and natural gas, has released large amounts of carbon dioxide (CO2) into the atmosphere. CO2 is a greenhouse gas, which means it traps heat in the atmosphere and contributes to climate change. Some of this CO2 is being absorbed by the ocean, where it reacts with seawater to form carbonic acid (H2CO3). This process, known as ocean acidification, lowers the pH of seawater and increases the concentration of bicarbonate ions (HCO3-) and carbonate ions (CO32-). CO₂ is a form of bicarbonate ion that is increasing in the ocean as a result of the burning of fossil fuels.
