Question

The Salt Story The salt pans in Marakkanam, a port town about 120 km from Chennai are the third largest producer of salt in Tamil Nadu. Separation of salt from water is a laborious process and the salt obtained is used as raw materials for manufacture of various sodium compounds. One such compound is Sodium hydrogen carbonate, used in baking, as an antacid and in soda acid fire extinguishers. The table shows the mass of various compounds obtained when 1 litre of sea water is evaporated. 34. Which compound in the table reacts with acids to release carbon dioxide?

Answer 2

C. $\[CaC{{o}_{3}}\]$ is the compound that reacts with acids to release carbon dioxide.

Explanation:

• Calcium carbonate responds by acidic solutions to give Carbon dioxide.

• Here reaction is held for Limestone Fizzing.

• Acid and carbonate gives salt, water, and carbon dioxide.

                $\[2HCl+CaC{{o}_{3}}\to CaC{{l}_{2}}+{{H}_{2}}O+C{{O}_{2}}\]$        

         Hydrochloric acid + Copper(II)Carbonate$\[\to \]$Copper(II)Cholride + Water + Carbon dioxide

• Acid with carbonate or hydrogencarbonate only form carbon dioxide.

• They also gave salt and water.
