The Correct Option is A
Solution and Explanation
Concept:
Dolomite is a carbonate mineral containing both calcium carbonate and magnesium carbonate. Its chemical formula is generally written as:
\[
CaMg(CO_3)_2
\]
It can be considered as a double carbonate of calcium and magnesium.
Step 1: Calcium carbonate is represented as: \[ CaCO_3 \] Magnesium carbonate is represented as: \[ MgCO_3 \]
Step 2: When calcium carbonate and magnesium carbonate occur together in a combined mineral form, the mineral formed is known as dolomite. \[ CaCO_3 + MgCO_3 \rightarrow CaMg(CO_3)_2 \]
Step 3: The compound: \[ CaMg(CO_3)_2 \] is called dolomite.
Step 4: Therefore, the mineral which is a solid solution or double carbonate of calcium carbonate and magnesium carbonate is: \[ \boxed{\text{Dolomite}} \]
