What is the primary chemical ion found in carbonate rocks?Multiple choice question.H2OCO3- -CO2C

Breakdown the Problem

1. Identify the chemical ions mentioned in the options.
2. Determine which ion is primarily associated with carbonate rocks.

Relevant Concepts

1. Carbonate rocks are primarily composed of carbonate minerals.
2. The main ion relevant to carbonate rocks is carbonate $(\text{CO}_3^{2-})$.

Analysis and Detail

1. The options provided are:

   • $\text{H}_2\text{O}$ (water)
   • $\text{CO}_3^{2-}$ (carbonate ion)
   • $\text{CO}_2$ (carbon dioxide)

2. Among these, $\text{CO}_3^{2-}$ (the carbonate ion) is the fundamental component of carbonate minerals such as calcite ($\text{CaCO}_3$) and dolomite ($\text{MgCO}_3$). It serves as the primary building block of these rocks.

Verify and Summarize

• After analyzing the options, it is clear that the primary chemical ion found in carbonate rocks is $\text{CO}_3^{2-}$.

Final Answer

The primary chemical ion found in carbonate rocks is $\text{CO}_3^{2-}$.
