Question

Quizplus · Accepted Answer

Calcium carbonate is more likely to dissolve in water that has a high concentration of carbon dioxide and is at colder temperatures. The presence of carbon dioxide forms carbonic acid when dissolved in water, which then reacts with calcium carbonate to form soluble bicarbonate, facilitating its dissolution. Colder water can hold more carbon dioxide, which aids this process.
