Carbonate

Carbonates are common minerals in the Earth's crust. A typical lab test for carbonates involves reacting them with dilute acid, which releases carbon dioxide.

Where are carbonates most commonly found?

• In the Earth's atmosphere

• In the Earth's mantle

• In the Earth's core

• In the Earth's crust

What is the typical method used in labs to test for carbonates?

• Reacting with dilute acid

• Mixing with water

• Heating the sample

• Exposing to sunlight

What gas is released when carbonates react with dilute acid?

• Hydrogen

• Oxygen

• Nitrogen

• Carbon dioxide

Which of the following is not a characteristic of carbonates?

• Releases oxygen

• Found in the Earth's crust

• Reacts with dilute acid

• Releases carbon dioxide

What confirms the presence of carbonates in a sample?

• Release of hydrogen

• Release of carbon dioxide

• Change in color

• Formation of a solid
