Write the state of hybridisation of carbon in `CO_(3)^(2-)` ion.

Explanation

To determine the state of hybridization of carbon in the carbonate ion \( \text{CO}_3^{2-} \), we can follow these steps:

### Step 1: Draw the Lewis Structure of \( \text{CO}_3^{2-} \)
- The carbonate ion consists of one carbon atom and three oxygen atoms.
- Carbon is the central atom, and it forms bonds with the three oxygen atoms.
- The total number of valence electrons is calculated as follows:
- Carbon has 4 valence electrons.
- Each oxygen has 6 valence electrons, and there are three oxygens: \( 3 \times 6 = 18 \).
