Of `PH_(3)` and `H_(2)S` which is more acidic and why ?

Explanation

To determine which compound, PH₃ or H₂S, is more acidic, we can analyze the properties of the elements involved and their ability to donate protons (H⁺ ions).

### Step-by-step Solution:

1. **Identify the Compounds**: We are comparing PH₃ (phosphine) and H₂S (hydrogen sulfide).

2. **Understand Acidity**: Acidity is defined by the ability of a compound to donate protons (H⁺ ions) in solution. The more readily a compound donates protons, the stronger the acid.
