What occurs when you add carbon dioxide to seawater?

Seawater is essentially NaCl + H2O. Adding CO2 will simply acidify the water, since CO2 + H2O ==> H2CO3 (carbonic acid). The NaCl can react to form Na2CO3 (sodium carbonate) and HCl, but all ions will be in solution, so there is no reaction, per se. Na^+ + Cl^- + 2H^+ + CO3^2- ==> no reaction

How caustic soda change into washing soda?

Caustic soda is sodium hydroxide - NaOH. Washing soda is sodium carbonate - Na2CO3. You can change washing soda into caustic soda with hydrochloric acid and electrolysis: Na2CO3 + 2HCl -> 2NaCl + CO2 + H2O ... then 2NaCl + 2H2O -> 2NaOH + H2 + Cl ... but it's not really practical to go the other way.


What do you do to not have a green pool while waiting to switch from cholorine to baquacil?

There really should not be too much of a problem when switching from CL to Baquacil. You just have to wait until the CL reading is down to zero and then start adding the products. The sun disepates the CL so quickly it should only take a couple days at most.
