Each of these compounds `Pt(NH_(3))_(6)Cl_(4), Cr(NH_(3))_(6)Cl_(3), Co(NH_(3))_(4)Cl_(3)` and `K_(2)PtI_(6)`has been dissolved in water to make its 0,001 M solution. Rank them in order of their increasing conductivity.

Explanation

To rank the given compounds in order of their increasing conductivity, we need to analyze the number of ions produced when each compound is dissolved in water. Conductivity in solutions is primarily due to the presence of ions, so the more ions produced, the higher the conductivity.

### Step-by-Step Solution:

1. **Identify the Compounds and Their Formulas:**
- \( \text{Pt(NH}_3\text{)}_6\text{Cl}_4 \)
- \( \text{Cr(NH}_3\text{)}_6\text{Cl}_3 \)
- \( \text{Co(NH}_3\text{)}_4\text{Cl}_3 \)
