    Sir I love your step by step teaching although am a jupeb student and I would love you to make a video on jupeb qualitative analysis practical for 2021cause it's a mixture of more than one salt
    Here's the question below 👇
    QUESTION 2: QUALITATIVE ANALYSIS
    You are provided with sample C, a mixture of 3 simple salts and are requested to perform the
    following experiments to identify the acidic radicals. Follow the instructions provided.
    Present your report in a tabular form with the headings, Test, Observation and Inference.
    Ensure your test tube is clean and dry.
    Test 1: Introduce C into the test tube provided, add 2 M HCl, test the gas evolved with lime
    water
    Test 2: Introduce C into the test tube provided, add conc H2SO4, test gas evolved with conc.
    Ammonia under the fume hood. Thereafter, add minimum MnO2 and heat.
    Test 3: Introduce C into the test tube provided, add conc H2SO4, introduce copper tunings’
    and heat.
    For each test carried out, give a brief description of the chemical reactions involved showing
    equations where relevant.
    [Total = 10 marks]
