Transcript of Coral Reef Calcification

Coral Reef Calcification What is it? Coral reef calcification is the rate at which coral absorb calcium from seawater to calcify their hard skeletons The chemical equation for Coral Calcification is
2HCO3 + Ca --> CaCO3 + CO2 + H2O


the products in the reaction are Calcium Carbonate, Carbon Dioxide, and water The reactants are Bicarbonate and Calcium As you can see in the equation below, the elements in this equation are:
2 hydrogen
2 carbon
6 oxygen
1 calcium There is NOT a catalyst in this equation and it IS a balanced equation As ocean acidification increase, Coral Reef Calcification will decrease, which will stop the growth of the Coral Reefs. There are many things that will result from this. Bibliography:

Fish will lose their homes The fish will die Some things affected by this:
tourist organizations and recreation(ex. snorkeling/scuba diving)
fisheries
hotels and restaurants based near reef ecosystems
Bicarbonate combines with calcium ions in the water to make calcium carbonate. In corals, calcium carbonate is the building block of coral reefs. As corals produce calcium carbonate they slowly add on to their existing reef structure allowing the reef to grow in size.
