Why is basicity of orthoboric acid one ?

Explanation

To understand why the basicity of orthoboric acid (H3BO3) is 1, we can break down the explanation into several steps:

### Step-by-Step Solution:

1. **Understanding Basicity**: Basicity refers to the number of hydrogen ions (H⁺) that an acid can donate or the number of hydroxide ions (OH⁻) it can accept. In the case of orthoboric acid, we need to analyze its behavior in water.

2. **Structure of Orthoboric Acid**: Orthoboric acid has the chemical formula H3BO3. Its structure consists of a boron atom bonded to three hydroxyl (OH) groups. The boron atom has a trigonal planar geometry.
