"As carbon dioxide dissolves in the water,or seawater in this case,it forms a weak acid(酸),carbonic acid,"Dore explains."And therefore,as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater,it drives the pH down,and makes it more acidic."...

1. Definition of Weak Acid: - A weak acid is defined as one that does not completely ionize in solution. This means that when a weak acid is dissolved in water, it does not produce a high concentration of hydrogen ions (H⁺). 2. Boric Acid Characteristics: - Boric acid (H₃BO...
