Calcium carbonate is most likely to dissolve in water with:
e. Lots of Carbon dioxide and colder temperature.
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.
