In what way can it be proved that `PH_(3)` is basic in nature ?

Explanation

To prove that PH₃ (phosphine) is basic in nature, we can follow these steps:

### Step 1: Understand the Structure of PH₃
Phosphine (PH₃) has a trigonal pyramidal structure with phosphorus at the apex and three hydrogen atoms at the base. The phosphorus atom has a lone pair of electrons.

### Step 2: Identify the Lone Pair
The presence of the lone pair on the phosphorus atom is crucial. This lone pair can accept protons (H⁺ ions), which is a characteristic behavior of bases according to Lewis theory.
