Chemistry - Mixtures
Cards in this deck (42)
- 1What are Mixtures?Substances which are not chemically bonded
- 2how many different substances does a mixture contain2 or more different substances
- 3mixtures are easily separated because…the chemicals in them are not joined together
- 4name 5 physical methods used to separate mixturesfiltration, crystallisation, simple distilation, fractional distillation
- 5if you evaporate off the solvent (the water) what would you see?the solute (salt)
Mum add pic - 6what is fractional distillation used to separate?crude oil
- 7What is chromatography. Give an example.all about separating different liquids
ink dyes - 8When salt dissolves does it vanish? Is mass lostNo it hasn't vanished and no mass is lost
- 9some solutes don't dissolve in certain solvents give an examplesalt wont dissolve in petrol
- 10give two other exciting uses for chromatographyidentifying blood samples and investigating chlorophyll
- 11name 4 separation methods
- 12which technique would be used to separate coloured ink in a mixtureChromatography
- 13Sodium chloride is used to do what in food?give it flavour and to preserve
- 14chlorine is used to do what in swimming pools?kill bacteria
- 15if iron and sulfur are put together next to each other what is it?mixture
- 16what is a mixture?something made up of two or more substances mixed together.
- 17when you put iron and sulfur together chemically dose it loose some of it's properties?yes
- 18when you chemically combine materials what happens to themchange in state and sometimes change in properties.
- 19The components of a mixture (are / are not) chemically combinednot
- 20What is Solute?the solid being dissolved
- 21What is Solvent?is the liquid it's dissolving into
- 22What is a Solutionis a mixture of a solute and a solvent that does not separate out.
- 23What is a Solubleit means it will dissolve
- 24What is Insolublemeans it will not dissolve
- 25What is a saturated solutiona solution that won't dissolve anymore solute at that temperature.
- 26What does Solubility meana measure of how much solute will dissolve
- 27What separation method is show? What would it separate?Chromatography
Dyes in Inks
- 28What separation method is shown? What would it separate?Distillation
Separates pure water from ink
- 29What is chromatographyseparating different liquids like ink dyes
- 30What is filtrationseparation of rock salt
- 31What is a mixturemixtures and substances that are not chemically joined
- 32What separation method is shown? What would it separate?Filtration and Evaporation
Rock salt and sand
- 33What separation method is shown? What would it separate?Fractional distillation
mixed liquids like crude oil
- 34In Filtration What mixtures are separated? How does it work? When would it be used?Insoluble solids from liquids
---
An insoluble substance cannot pass through filter paper
---
To remove solids before waste water is purified - 35What is Solutethe solid being desolved
- 36What is Solventthe liquid the solute is dissolving in
- 37What is Solutiona mixture of solute and a solvent that doesn't separate
- 38What is solublesomething that will dissolve
- 39What is insolublesomething that will not dissolve
- 40What is saturatedsomething that won't dissolve anymore solute at that temperature
- 41Solubilitymeasure of how much solute will disolve
- 42There are four sepreation techniques, what are theyFilteration
Evaporation
chromatography
distillation
