Method. pour 1 cm3 of each known chloride solution into 5 test tubes. clean the nichrome wire by dipping it in dilute hydrochloric acid. dip the nichrome wire into solution and hold the tip in a blue bunsen flame. record the colour of the flame. repeat for the following solutions and make sure to clean the wire after each test.
New 2016 Aqa Chemistry Required Practical Sheet Neutralisation The purpose of this handbook. the required practical activities listed in the gcse chemistry specification (8462) have been written to ensure that students have the opportunity to experience all of the apparatus and techniques (at) criteria required by ofqual. in this guide we suggest methods for carrying out the required practical activities. Testing for ammonium ions. dissolve a little solid salt in a test tube using distilled water. add dilute naoh solution and heat gently. remove the flame, and then hold a piece of damp red litmus paper near the mouth of the test tube. record any change in colour.
