Chemistry Tuition Singapore Secondary Science Tuition – Solution and Suspension
SOLUTIONS
- Asolution is a homogeneous mixture of a solute and a solvent, that is, the solute and the solvent are mixed evenly in every part of the solution.
- Solvent is the substance that dissolves another substance. It forms the bulk of a solution.
- Solute is the substance that is being dissolved by another substance.
SUSPENSIONS
- It is a heterogeneous mixture of a solid-liquid.
- The solute does not dissolve in the solvent. Examples are chalk powder mixes with water or sand placed in water.
The characteristics of a suspension from a mixture of solid-liquid are as follows:
- There are particles settling at the bottom of the liquid after being left standing for a while.
- It scatters light as it does not allow light to pass through it. This is
because the solute particles are large enough to scatter light or block the passage of light. - There are particles remaining on the filter paper as residue after filtration. This is because the size of the solute particles is too large to pass through the filter paper.
- It appears cloudy because there are particles suspending in the solvent.
