- testing for carbonates
- add hydrochloric acid into test tube for form a gass
- it is a carbonate if lime water turns cloudy
- add hydrochloric acid into test tube for form a gass
- testing for sulfates
- hydrochloric acid and barium chloride
- if it is a sulphate then it will form a white precipitate
- hydrochloric acid first so that the chloride is taken out of solution
- hydrochloric acid and barium chloride
- testing for halides
- add dilute nitric acid and then silver nitrate
- chlorine is white
- bromide is cream
- iodide is yellow
- add dilute nitric acid and then silver nitrate
- tests for different gasses
- chlorine
- use litmus paper
- it should turn from red to white
- use litmus paper
- oxygen
- relighting a glowing splint
- carbon dioxide
- bubbling lime water
- lime water should turn cloudy
- bubbling lime water
- hydrogen
- squeaky pop test with a lit splint
- chlorine
- pure and impure
- pure is made out of one type of atom
- impure is made up of more than one type of atom
- formulation is another word for a mixture made for a specific job
- separation methods
- chromatography - mass
- distillation - boiling point
- filtration - states of matter
- chromatography
- mobile phase
- the solvent moving up the paper
- stationary phase
- the chromatography paper
- FR value
- distance moved by substance -------------distance travelled by solvent
- mobile phase
- testing for cations
