Identifying Ions Gcse Chemistry Study Mind This required practical requires: testing for metal ions using flame tests and sodium hydroxide solution this required practical also requires testing for the non metal ions: carbonates, halides and sulfate. Aqa chemistry gcse: required practical 7 identifying ions. how do you carry out a flame test to identify metal ions? click the card to flip it ๐. clean a platinum wire loop by dipping it in hcl and then holding it in the blue flame until it burns without any colour. dip the loop into the sample you want to test and put it into the blue. 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. Method. place a 2 cm3 of limewater in a clean test tube. add a little dilute hydrochloric acid to the unknown solution. if you see bubbles, transfer the gas produced to the limewater using a delivery tube. repeat this process for the known sodium solutions to identify carbonates ions.

Teachersโ notes. required practical activity. apparatus and techniques. preparation of a pure, dry sample of a soluble salt from an insoluble oxide or carbonate, using a bunsen burner to heat dilute acid and a water bath or electric heater to evaporate the solution. at 2, at 3, at 4, at 6. Aqa gcse chemistry required practical 7 : identifying ions. summary: click the card to flip ๐. in this investigation you will analyze a range of known ionic compounds by flame testing and the addition of acids, barium chloride and silver nitrate. you will then apply the knowledge you gain to identify the ions in an unknown compound.
