Since the beginning of the Industrial Revolution, how much has the pH dropped in the oceans? 0.9 0.7 0.1 0.3

0.1

Explanation:

pH of ocean has decreased from 8.2 to 8.1, it means by 0.1, which refers that slowly ocean water is moving towards getting acidic and that will be very harmful for marine life and human population as well.

Industrial revolution is one of the main cause of decreasing pH in oceans as it leads to pollution, combustion of fossil fuels and global warming which releases more amount of CO2. Most of this CO2 dissolves into seawater, mix with H2O and form carbonic acid (H2CO3), which is acidic in nature.

Hence, the pH is dropped in the oceans by 0.1.
