Question

Dilute acid does not produce carbon dioxide on being treated with: a. Marble b. Lime c. Baking soda d. Limestone ​

Answer 1

Dilute acid does not produce carbon dioxide on being treated with(b) Lime

Explanation:

• Marble: Marble is composed up of white calcite crystals and coloured mica inclusions; the grains are stuck together like jigsaw puzzle pieces in a marble.
• Lime: Lime is a calcium-containing inorganic mineral that is generally made up of oxides and hydroxides, most often calcium oxide and calcium hydroxide. It's also the name for calcium oxide, which is found in volcanic ejecta as a byproduct of coal-seam fires and in altered limestone xenoliths.
• Baking Soda: Baking soda is a leavening agent that is commonly used in baked goods such as cakes, muffins, and cookies. It's a white crystalline powder that's inherently alkaline, or basic. It's also known as sodium bicarbonate.
• Limestone:  ​Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the forms of calcite or aragonite. However, clay, iron carbonate, feldspar, pyrite, and quartz are also common minor ingredients. The grains are frequently small pieces of prehistoric animal shells.

Answer 2

Marble, Limestone and baking soda have carbonates which produces CO2 gas. Lime contains Hydroxide which will not produce CO2. Marble, limestone, and baking soda are all metal carbonates or bicarbonates. When they interact with a dilute acid, carbon dioxide is produced. When lime, which is calcium oxide, combines with a dilute acid carbon dioxide is not produced.

CaO + dil 2HCl → CaCl2 + H2O

Thus, lime when reacts with an acid then it produces salt and water but it does not produce carbon dioxide.
