Total alkalinity of seawater and calciumcarbonate formation
« on: June 15, 2022, 07:50:58 AM »
Hi everyone,

My question is, why exactly does the total alkalinity (TA) of seawater decrease when calciumcarbonate is formed?
I have an explanation but I don't know if it's correct.
Carbonate ions are partly responsible for the TA of the ocean. When CaCO3 is formed, less carbonate ions can partake in oceans total alkalinity, whereby the alkalinity decreases because less protonacceptors (such as carbonate) are present.
Is this correct? It is for my master thesis.

Kind regards,
K

Check the  solubility of calciumcarbonate. Why can snails, shellfisch,  corales, oysters,  etc. exist.

Hint: is a solid part of the solution?
