Question

Calcium carbonate is most likely to dissolve in water with which characteristics?

Answer 1

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.
