Carbonato

The video explains that carbonates are minerals found throughout the earth's crust. It describes a common laboratory test to identify carbonates, which involves reacting the mineral sample with dilute acid to release carbon dioxide.

What type of minerals are carbonates commonly found as?

• Sedimentary

• Metamorphic

• Igneous

• Minerals in the earth's crust

What is the primary method used in laboratories to test for carbonates?

• Heating the sample

• Reacting with dilute acid

• Using a magnet

• Dissolving in water

Which gas is released when carbonates react with dilute acid?

• Nitrogen

• Carbon dioxide

• Oxygen

• Hydrogen

What is the purpose of using dilute acid in the carbonate test?

• To release carbon dioxide

• To change the mineral's color

• To increase the mineral's temperature

• To dissolve the mineral

Which of the following is NOT a characteristic of carbonates?

• Releases carbon dioxide

• Releases oxygen gas

• Reacts with dilute acid

• Found in the earth's crust
