Dear Year 10 students,
Following are the standards that will be covered in the unit test on Thursday, 9th March. I have also included the details of chapters and page numbers. Year 10 IGCSE Chemistry Standards, chapters and page numbers for unit test on Thursday 13- Describe the manufacture of lime (calcium oxide) from calcium carbonate (limestone) in terms of thermal decomposition Name the uses of calcium carbonate in the manufacture of iron and of cement Name some uses of lime and slaked lime as in treating acidic soil and neutralizing acidic industrial waste products, e.g. flue gas desulfurization 8.1- Describe and explain the importance of controlling acidity in soil 8.3- Demonstrate knowledge and understanding of preparation, separation and purification of salts as examples of some of the techniques specified in section 2.2.2 and the reactions specified in section 8.1 8.3(S)- Demonstrating knowledge and understanding of the preparation of insoluble salts by precipitation Suggest a method of making a given salt from suitable starting material, given appropriate information 8.4 - Describe the following tests to identify: aqueous cations: aluminium, ammonium, calcium, chromium(III), copper(II), iron(II), iron(III) and zinc (using aqueous sodium hydroxide and aqueous ammonia as appropriate) (Formulae of complex ions are not required) cations: use of the flame test to identify lithium, sodium, potassium and copper(II) anions: carbonate (by reaction with dilute acid and then limewater), chloride, bromide and iodide (by reaction under acidic conditions with aqueous silver nitrate), nitrate (by reduction with aluminium), sulfate (by reaction under acidic conditions with aqueous barium ions) and sulfite (by reaction with dilute acids and then aqueous potassium manganate(VII)) 8.4 gases: ammonia (using damp red litmus paper), carbon dioxide (using limewater), chlorine (using damp litmus paper), hydrogen (using lighted splint), oxygen (using a glowing splint) and sulfur dioxide (using aqueous potassium manganate(VII) Cambridge IGCSE Text book- Chapter 5- Sub-divisions 5.8, Preparing insoluble salts- 5.9, Strong and weak acids and alkalis – 5.11 Table 12.1 page- 297,Table 12.2 page- 298, Table 12.3 page 299, Table 12.4 Page 300 Complete Chemistry Text book Chapter 11- Subdivisions 11.6, 11.7 and 11.8 Tables on pages 279, 281and 282 Comments are closed.
