| Question | Answer |
|---|---|
| True or False? A mixture is made of more than one substance joined together. | FALSE |
| Which type of mixture has an opaque appearance? | Colloid |
| What happens to the solid in a suspension? | It settles out |
| Which separation method is used to separate an undissolved solid (e.g. sand) from a liquid? | Filtration |
| Name the 3 pieces of apparatus that are needed for filtration. | Filter paper, Filter funnel, Conical Flask(or Beaker) |
| A solution is formed by dissolving a salt in water. What is the solute in this example? | Salt |
| A solution is formed by dissolving a salt in water. What is the solvent in this example? | Water |
| What word is used to describe a solid that cannot dissolve in a liquid? | Insoluble |
| What is a saturated solution? | A solution that contains so much dissolved solute that no more solute can dissolve in it. |
| How does temperature affect the amount of solid that can dissolve in a liquid? | The higher the temperature, the more solid can dissolve. |
| Which separation method is used to separate a dissolved solid (e.g. salt) from a solution? | Evaporation |
| What do you have to do to salt water to evaporate the water? | Heat it. |
| True or False? A mixture is made of more than one substance not joined together. | TRUE |
| What type of mixture is transparent (see-through)? | A solution |
| What does filtration separate from a liquid? | Insoluble solid/undissolved solid |
| A solution is made by adding as much salt as possible to water until no more dissolves. How would you describe this solution? | Saturated |
| 20g of salt is dissolved in 100g of water. What is the mass of the salt solution? | 120g |
| What type of mixture can be separated by evaporation? | A dissolved solid from a liquid/a solution. |
| What separation technique is used to separate a liquid from a mixture? | Distillation |
| What are the two stages of distillation? | Evaporation of the liquid, Condensation of the gas. |
| What is the name of the piece of apparatus labelled ‘A’? | Liebig Condenser/Condenser |
| A solution of salt and water is distilled using the apparatus in question 9. What would you expect to collect in the beaker? | Pure water/water |
| What separation technique would you use to separate the colours in brown ink? | Chromatography |
| Mixture X is separated by chromatography. Which two substances (A,B,C,D)does mixture X contain? | C and D |
| In everyday language what is a "pure" substance? | A substance that has had nothing added to it and is in its "natural" state |
| What do we call a substance that doesn't dissolve? | Insoluble |
| In chemistry what is a "pure" substance? | A substance made of a single element or compound |
| What do we call a substance that does dissolve? | Soluble |
| What do we use to separate an insoluble solute from solution? | Filtration |
| What do we use to separate a soluble solute from solution? | Evaporation |
| What is the solid that dissolves called? | Solute |
| What do we use to separate a solvent from solution? | Distillation |
| What is the liquid the substance dissolves in called? | Solvent |
| What do we use to separate two or more coloured solutions? | Chromatography |
| What do we call a mixture of a solvent and solute together? | Solution |
| What do we call the point where no more solute will dissolve? | Saturation point |
| Give three ways of increasing the rate of dissolving | Stir and heat |
| List the two pieces of equipment needed for filtration | 1) filter funnel, 2) filter paper |
| What is the substance left in the filter paper after filtration called? | Residue |
| What is the liquid that has been filtered called? | Filtrate |
