| A | B |
|---|
| Finding the moisture content of a brown coal sample | Gravimetric analysis |
| Testing the acid concentration in a wine sample | Acid-base titration |
| Testing a red soft drink to see if a mixture of food dyes were used | Paper chromatography |
| Determining whether a salt was NaCl or KCl | Flame test |
| Determining the amount of alcohol in a wine sample | Redox titration |
| Measures concentration of metals by measuring the light they absorb | Atomic Absorption Spectroscopy |
| Measures concentration of coloured or UV-absorbing compounds | UV-Visible Spectroscopy |
| Can distinguish between proteins or other polymers based on their size | Electrophoresis |
| Determines concentration by comparing a solution’s colour to that of a known solution | Colorimetry |
| Able to detect quantities as low as (10)-12 g but limited to substances that can be vapourised | Gas-liquid chromatography |
| A separation technique that can handle compounds with relative molecular masses over 1000 | High Performance Liquid Chromatography |
| A technique invented by Australia’s Alan Walsh in the 1950s | Atomic Absorption Spectroscopy |
| Like paper chromatography but uses powder-covered plates as the stationary phase | Thin-layer chromatography |
| More complex than flame tests but identification is also based on light emitted by a heated sample | Atomic Emission Spectroscopy |
