What are identification tests of phenol?
You add a specific ionic compound in a solution to determine if phenol or any of its derivatives are present. Ferric chloride (FeCl3) for example, can be used for such tests. Basically, when you mix the solution with the compound, the ions will interact with the phenol molecules or groups, and as a result, the solution will briefly change color. If there is no colour change in the solution, this suggest there is no phenol or phenol-based molecules in your solution.
Can you tell if a mixture is a mechanical mixture by looking at it?
You can recognize a mechanical mixture because it consists of different substances that you can see and separate out of it. Examples of mechanical mixtures are cereal and milk in a bowl, soil that contains small pebbles, twigs, and bits of leaves.
Biochemical tests are used to determine what?

When copper sulphat is stirred into a water water turns blue what two tests carry out to see whether this mixture is suspension or a solution?
A suspension is cloudy or will not allow light through, a solution is clear even though it can be colored. One way to test is to shine a light through the water mixture and see if it allows light to come through without breaking it up or dimming it. If it does it's a solution, if not its a suspension.
