1228 - How can compounds be identified using chemical properties?

Compounds can be identified using chemical properties in several ways:

1. Reactions with other substances: Different compounds react with other substances in different ways. For example, some compounds may change color, release gas, or produce a new substance when mixed with acid or base.

2. Change in smell: Compounds can have distinct smells, and these smells can change when a reaction occurs.

3. Formation of crystals: Some compounds can form crystals with distinct shapes or colors, which can help identify them.

4. Flammability: Some compounds can catch fire easily, while others don't burn at all.

5. pH level (Acidic or Basic): Compounds can be acidic or basic, and changing the pH level can help identify them.

By using these chemical properties, scientists can figure out the identity of a compound.
