Cation Test

The cation test is a test to determine the cation present in a sample solution. The cation test is carried out as part of quantitative analysis in identifying the ions present in a solution. Cation test starts with the use of sodium hydroxide solution and ammonia solution. Different cations react to produce different observations that can be used to identify the specific cation present in the solution. 00:00 - Introduction 00:24 - Cation test using sodium hydroxide solution 00:54 - Ammonium ion 02:23 - White precipitate with a few drops of sodium hydroxide solution 04:29 - Lead (II) ion 05:42 - Aluminium ion 06:06 - Coloured precipitates 06:12 - Copper (II) ion 06:22 - Iron (II) ion and iron (III) ion 06:55 - Confirmatory test for iron (II) and iron (III) ions using potassium hexacyanoferrate and potassium thiocyanate 08:31 - Trick to remember colour of iron (II) and iron (III) ions 09:10 - Cation test using ammonia solution 09:26 - Calcium ion 10:31 - Magnesium ion 10:57 - Zinc ion 11:37 - Magnesium ion 11:56 - Coloured precipitates 12:16 - Dark blue solution of copper (II) ions ALSO WATCH: Soluble and Insoluble Salts -    • Soluble and Insoluble Salts // Easy Way to...   Catering for IGCSE and SPM students.
