Can carbon dioxide be removed from water by using a neutralizing filter with limestone chips?

The removal of carbon dioxide from water using a neutralizing filter containing limestone chips is indeed possible and is indicated by the affirmative answer. Limestone primarily consists of calcium carbonate, which reacts with carbon dioxide in water to form bicarbonate. This chemical reaction effectively lowers the concentration of carbon dioxide in the water.

When water containing dissolved carbon dioxide passes through a neutralizing filter filled with limestone, the following process occurs: The calcium ions from the limestone react with the bicarbonate ions formed from the carbon dioxide, effectively removing it from the water and resulting in the formation of calcium bicarbonate. This not only helps in reducing the levels of carbon dioxide but also can increase the pH of the water, as the acidity is neutralized.

This process is particularly useful in water treatment systems where the pH needs to be adjusted and where carbon dioxide removal is necessary. Therefore, carbon dioxide can be effectively removed from water using limestone chips in a neutralizing filter, supporting the choice that confirms this capability.
