Worked practice questions

A HOMOGENEOUS mixture is one in which:

  1. The components are easily seen as separate particles
  2. Composition is uniform throughout (like sugar water)
  3. Two or more solids combine without dissolving
  4. Particles of solid sit at the bottom and liquid floats above
Show answer and solution

Correct answer: B. Composition is uniform throughout (like sugar water)

Homogeneous mixtures have uniform composition throughout. **Examples:** salt water, sugar water, brass, air. Heterogeneous mixtures show distinct components. Homogeneous mixtures are also called solutions.

In LEMON JUICE (sugar dissolved in water), the SOLUTE is:

  1. Water, present in larger amount in the drink
  2. Lemon juice, providing the colour and taste
  3. Sugar, dissolved in water in smaller amount
  4. Both sugar and water are solutes together
Show answer and solution

Correct answer: C. Sugar, dissolved in water in smaller amount

In a solution, the SOLVENT is the larger amount (water in lemon juice). The SOLUTE is the dissolved substance in smaller amount (sugar). Lemon juice itself is also part of the solution.

A SATURATED solution is one in which:

  1. Less solute is dissolved than the maximum capacity
  2. More solute is dissolved than the maximum capacity (unstable)
  3. The temperature is much higher than room temperature
  4. The maximum possible solute is dissolved at that temperature
Show answer and solution

Correct answer: D. The maximum possible solute is dissolved at that temperature

A saturated solution holds the MAXIMUM solute that can dissolve at the given temperature. Unsaturated holds less; supersaturated (unstable) holds more. Solubility usually rises with temperature for solids.
