Webwould have a pH of about 4.2. Seawater with a pH of less than 6.5 is lethal to most coastal marine organisms and oceanic species are expected to be more sensitive. The pH of the water from the scrubber could be raised by partial neutralisation with calcium carbonate prior to discharge but very WebCO 2 and pH. The equation above also illustrates carbon dioxide’s role as a buffer, regulating the pH of the ocean. Recall that pH reflects the acidity or basicity of a solution. The pH …
WebFrom the relations above it can be seen that the ability of seawater to buffer changes in its pH as CO 2 is added depends on the amount (or concentration) of CO 3 2-present.
