Homogeneous mixtures can have variable composition
A homogeneous mixture is a type of mixture in which the components are uniformly distributed throughout the mixture. This means that the composition of a homogeneous mixture is the same throughout, regardless of the sample size or location within the mixture.
Explanation:
Homogeneous mixtures:
- Homogeneous mixtures are also known as solutions.
- In a homogeneous mixture, the particles of the different substances are evenly distributed and cannot be visually distinguished.
- Examples of homogeneous mixtures include saltwater, sugar dissolved in water, and air.
Variable composition:
- The composition of a mixture refers to the relative amounts of the different substances that make up the mixture.
- In a homogeneous mixture, the composition can vary.
- The composition can be changed by adding more or less of one of the substances.
- For example, in a saltwater solution, the composition can be changed by adding more salt or more water.
- The ratio of salt to water can vary, resulting in different concentrations of the solution.
Contrary options:
- Option b) states that homogeneous mixtures have fixed composition, which is incorrect.
- Option c) states that heterogeneous mixtures have fixed composition, which is also incorrect.
- Option d) states that a salt solution is a heterogeneous mixture, which is incorrect. Salt dissolved in water forms a homogeneous mixture.
Conclusion:
The correct statement is option a) Homogeneous mixtures can have variable composition. This is because the composition of a homogeneous mixture can be changed by altering the amounts of the substances present, resulting in different concentrations of the mixture.
