GCSE Combined Science · key term
A mixture formed when a solute dissolves in a solvent.
Used by AQA and Edexcel
Specification 5.3.2.5 · Paper 3
Revise: Concentration of SolutionsMany chemical reactions take place in solutions. When salt dissolves in water, the salt is the solute, the water is the solvent, and the resulting mixture is a solution.
Specification Calculations involving masses, Methods of separating and purifying substances · Paper 3, Paper 4
Revise: Relative masses, percentage composition and solution concentrationTogether they form a solution. For example, when sodium hydroxide dissolves in water, sodium hydroxide is the solute and water is the solvent.
Use the final volume of the solution, not simply the volume of solvent used to dissolve the solute.
Use the final volume of the solution, not the volume of solvent added.
Filtration cannot remove a dissolved salt: the salt passes through the filter paper with the solution.
