Adjust the pH of the solution to 5.3 0.1, if necessary (Solution A). Why is hydrogen carbonate called bicarbonate? What type of plant can we use to investigate the rate of photosynthesis? Carbon dioxide and seawater Carbon dioxide, which is naturally in the atmosphere, dissolves into seawater. When enough carbonic acid is formed it neutralizes the lime water, which is a base and makes the solution an acid. For over 80 years, Carolina has been providing the highest-quality living organisms and cultures available. An aqueous solution of sodium carbonate has basic pH because carbonate ions hydrolize to yield hydroxide ions plus bicarbonate ions. If you immerse pondweed in a solution containing carbon dioxide, it will gradually deplete the carbon dioxide from the solution unless the carbon dioxide removed during photosynthesis is replaced somehow.
