Why is only increasing the pH of the ocean not enough to restore the ocean’s equilibrium? How does decreasing the pH decrease carbonate (CO₃²⁻) concentration? Some calcifiers can use bicarbonate (HCO₃⁻) to make their shells. How will they be affected by the decrease in pH?

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
