  • What is the confirmation test for phthalic acid?

    Phenols condense with phthalic anhydride in the presence of concentrated H2SO4, Phenol condeses to give phenolphthalein which gives a dark pink colour with NaOH solution.
    This is called phthalein dye test.

  • What is the confirmation test for acid?

    (c) Ester Test:
    Heat the mixture in a dry test tube in a water bath.
    Pour the reaction mixture into a beaker carefully containing water.
    Neutralise the excess sulphuric acid.
    If a sweet smelling substance is sensed then it indicates the presence of acid.15 juil. 2020

  • What is the confirmatory test for cinnamic acid?

    Confirmatory test Take 0.2 g sample + 1 ml con. HSO . Greenish to brownish red colorCinnamic acid is confirmed Conclusion: From the results of above experiments it is concluded that the given sample is cinnamic acid.

  • What is the confirmatory test for cinnamic acid?

    (a) Note physical characteristics - solid, liquid, colour and odour. (b) Perform an ignition test (heat small amount on metal spatula) to determine whether the compound is aliphatic or aromatic (i.e. luminous flame - aliphatic; sooty flame - aromatic).
