Classify colloids where dispersion medium is water. State their characterstics and write one example of each of these classes.

Explanation

To classify colloids where the dispersion medium is water, we can categorize them based on the state of the dispersed phase. Here’s a step-by-step solution:

### Step 1: Define Colloids
Colloids are heterogeneous mixtures with particle sizes ranging from 1 nm to 1000 nm. They consist of two phases: the dispersed phase (the substance in smaller amount) and the dispersion medium (the substance in larger amount).

### Step 2: Identify the Dispersion Medium
In this case, the dispersion medium is water, which is in liquid form.
