The solvent boils and then condenses and the solvent is collected. 15 of 36 Filtrate The liquid that passes through a filter 16 of 36 Filtration Method to separate a mixture of a liquid and an insoluble solid by passing it through paper or other material which only allows the liquid through . 17 of 36 Fractional distillation A process in which a mixture of liquids with different with different boiling points is separated by distillation 18 of 36 Freezing Point The temperature at which liquid turns into a solid 19 of 36 Immiscible liquids that do not mix together but form two separate layers. 20 of 36 Indicators Substance which change colours the PH of a solution alters. 21 of 36 Insoluble A substance that does not dissolve in a solvent. 22 of 36 Melting point The temperature at which a solid turns into a liquid. 23 of 36 Miscible Liquids that mix together. 24 of 36 Neutralisation A reaction in which an acid reacts with a base pro ducting a salt and water. 25 of 36 Precipitate A solid formed by the reaction of two solutions. 26 of 36 saturated solution A solution in which no more solute will dissolve at that temperature. 27 of 36 Solubility A measure of how much solute dissolves in a solvent. 28 of 36 soluble When a substance can dissolve in a solvent 29 of 36 Solute The substance that dissolves in a solvent 30 of 36 Solution A mixture of a solute dissolved in solvent. 31 of 36 Solvent A liquid in which a solute dissolves. 32 of 36 Sublimation When a solid changes directly into a gas without melting first. 33 of 36 Suspension A mixture of insoluble solid particles spread through a liquid. 34 of 36 Titration A way of measuring the exact volume of acid and alkali needed for neutralisation 35 of 36 Universal Indicator Mixture of dyes which display a range of different colours asa the pH of a solution changes. 36 of 36
