💬 Think about it
Think of ORS, the drink that fights dehydration. Stir sugar and salt into water and every sip tastes identical. But stir chalk powder into water and it looks patchy. Some mixtures are even, some are not. Let's sort them out.
What is the difference between uniform and non-uniform mixtures?
- Salt and sugar in water spread evenly — a uniform mixture.
- That is why every sip of ORS tastes the same.
- Chalk powder, sand, or sawdust in water is patchy.
- These uneven mixtures are non-uniform mixtures.
Example:
Homemade ORS is uniform; muddy water with sand settling is non-uniform.
Uniform mixture
Non-uniform mixture
Components spread evenly.
Components are not evenly spread.

Important Points
- Salt and sugar in water form a uniform mixture.
- Chalk, sand, or sawdust in water form non-uniform mixtures.
- A uniform mixture tastes the same in every part.
Important Definitions
- Uniform mixture — a mixture whose components are spread evenly and cannot be seen separately.
- Non-uniform mixture — a mixture whose components are not evenly spread and can be seen separately.
