Which one of the following will NOT produce carbon dioxide on reacting with an aqueous solution of hydrochloric acid?
Options
- ALimestone
- BQuick Lime
- CChalk
- DMarble
Correct answer
B. Quick Lime
Step-by-step solution
In the given options, marble, limestone, and baking soda are all either metal carbonates or bicarbonates. All these when react with a dilute acid then they produce carbon dioxide. Whereas lime which is calcium oxide when react with a dilute acid then they do not produce carbon dioxide. For example, CaO + dil. 2 HCl CaCl ₂+ H ₂ O Thus, lime when reacts with an acid then it produces salt and water but it does not produce carbon dioxide.
