Quick explanation

Explain the following terms: (a) a solvent is a substance that dissolves a solute (b) a solute is a substance that gets dissolved in a solvent (c) a solution is a mixture of one or more solutes dissolved in a solvent (d) a saturated solution is one that has the highest concentration of a solute that can dissolve in the solvent at a given temperature (e) residue is the solid that remains after processes like evaporation, distillation, or filtration (f) filtrate is the liquid or solution that has gone through a filter

  • This point belongs to Experimental design, especially Experimental design outcomes.
  • You need to be able to explain the following terms: (a) a solvent is a substance that dissolves a solute (b) a solute is a substance that gets dissolved in a solvent (c) a solution is a mixture of one or more solutes dissolved in a solvent (d) a saturated solution is one that has the highest concentration of a solute that can dissolve in the solvent at a given temperature (e) residue is the solid that remains after processes like evaporation, distillation, or filtration (f) filtrate is the liquid or solution that has gone through a filter.
  • The key ideas to know are Define and Explain.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Description

Definitions of Solutions

A solvent dissolves a solute. A solute is dissolved in a solvent. A solution is a mixture of solutes in a solvent. A saturated solution has the maximum solute that can dissolve at a given temperature. Residue is the solid left after processes like evaporation, and filtrate is the liquid that passes through a filter.
