Calcium carbonate is most likely to dissolve in water with:

e. Lots of Carbon dioxide and colder temperature.

Step-by-step explanation:

  • Calcium carbonate is very sparingly soluble in water. However, it has been observed to dissolve in cold water with higher concentration of Carbon dioxide.
  • The reason behind the observation is the formation of Calcium bicarbonate which is soluble in water.
  • Higher concentration of Carbon dioxide in water turns it acidic. When this acidic water reacts with calcium carbonate it forms Calcium bicarbonate which is soluble in water.
  • So,Calcium carbonate is most likely to dissolve in water with lots of Carbon dioxide and colder temperature.
