Which statement accurately describes what this graph shows?

• As pH decreases, CO₃^2- (carbonate) is less concentrated

• At pH 6-9, HCO₃^- is at a low concentration

• There is no correlation between carbonate ion concentration & pH

~92% of the carbon dioxide dissolved in the ocean ends up as

• Bicarbonate

• Carbonic acid

• Carbon dioxide

• Carbonate
