Correct the following statements by changing the under lined part of the sentence (Do not change the whole sentence)
The complex `[Co(NH_3)_5Cl]Cl_2` in aqueous solution gives three `Cl^(-)` ions.

Explanation

To correct the statement, we need to analyze the complex `[Co(NH_3)_5Cl]Cl_2` and understand how it dissociates in aqueous solution.

1. **Identify the complex and its components**: The complex is `[Co(NH_3)_5Cl]Cl_2`. Here, `[Co(NH_3)_5Cl]` is the coordination sphere, and `Cl_2` indicates that there are two chloride ions outside the coordination sphere.

2. **Dissociation in aqueous solution**: When this complex is dissolved in water, it dissociates into its components. The dissociation can be represented as follows:
\[ [Co(NH_3)_5Cl]Cl_2 \rightarrow [Co(NH_3)_5Cl]^+ + 2Cl^- \]
