CHEMISTRY || Types of Separation

What physical separation technique is BEST used to separate sand from a mixture of sand, salt, and water? → Filtration separation

What physical property allows filtration to separate sand from saltwater? → Sand is insoluble in water and has larger particles that are trapped by the filter

What is the BEST technique used to separate plant pigments and dyes? → Paper chromatography

What physical property allows paper chromatography to separate plant pigments and dyes? → Different substances travel at different rates through the paper

What is the BEST technique to separate iron filings from sand? → Magnetic separation

What physical property is used to separate iron filings from sand? → Magnetism

What is the BEST technique to separate water from boiled rice? → Decanting

What is the BEST technique to separate sand from water? → Filtration separation

What property is used during filtration? → Particle size and insolubility

What is the BEST technique to separate salt from saltwater when you want to keep the salt? → Evaporation

What physical property is used in evaporation? → Difference in boiling points

What is the BEST technique to separate and collect water from saltwater? → Distillation

What physical property is used in distillation? → Different boiling points

What is the BEST technique to separate oil and water when they form different layers? → Density separation

What physical property is used to separate oil and water? → Density

What is the BEST technique when a mixture needs to be separated by rapidly spinning it? → Centrifuge

What physical property allows a centrifuge to separate components? → Differences in density

What is the BEST technique to separate dissolved substances that have different solubilities? → Fractional crystallization

What physical property is used in fractional crystallization? → Differences in solubility

What is the BEST technique for physically sorting pieces of a mixture apart? → Mechanical separation

What physical property can mechanical separation use to separate different-sized pieces? → Size

A student uses a magnet to remove iron from sand. What technique is being used? → Magnetic separation

A student carefully pours liquid away from a solid that settled at the bottom. What technique is being used? → Decanting

A student heats saltwater until the water is gone and salt remains. What technique is being used? → Evaporation

A student heats a mixture of liquids and collects one liquid after its vapor condenses. What technique is being used? → Distillation

A student separates colored pigments by how far they travel across paper. What technique is being used? → Paper chromatography

A student spins a mixture very quickly to separate its components. What technique is being used? → Centrifuge

A student cools a solution so different substances form crystals based on their solubility. What technique is being used? → Fractional crystallization

A student physically sorts larger pieces from smaller pieces of a mixture. What technique is being used? → Mechanical separation

What method separates a solid from a liquid using a filter? → Filtration separation

What method separates a magnetic substance from a nonmagnetic substance? → Magnetic separation

What method separates a liquid from a settled solid by pouring? → Decanting

What method removes a liquid as vapor and leaves a dissolved solid behind? → Evaporation

What method separates substances using different boiling points? → Distillation

What method separates substances using differences in density? → Density separation

What method separates substances using rapid spinning? → Centrifuge

What method separates substances based on how far they travel through paper? → Paper chromatography
