Colloidal solutions are heterogeneous and consist of two phases, namely (i).......and (ii)............

Explanation

To solve the question, we need to identify the two phases that make up a colloidal solution. Colloidal solutions are indeed heterogeneous mixtures, and they consist of two distinct components.

### Step-by-Step Solution:

1. **Understanding Colloidal Solutions**:
- Colloidal solutions are mixtures where one substance (the dispersed phase) is distributed evenly throughout another substance (the dispersion medium).

2. **Identifying the Phases**:
