Worked practice questions
Which of these is a homogeneous mixture?
- Salt mixed with sugar
- Grains mixed with pulses
- Sugar dissolved in water
- Sand mixed with stones
Show answer and solution
Correct answer: C. Sugar dissolved in water
In a sugar solution the components are uniformly distributed, so its composition is the same throughout.
The components of a mixture can be separated by which methods?
- Chemical reactions only
- Electrolysis of the mixture
- Burning in pure oxygen
- Physical methods like filtration
Show answer and solution
Correct answer: D. Physical methods like filtration
Mixture components keep their own identity, so hand-picking, filtration, crystallisation or distillation can separate them.
