The solution of the above question is given below with explanation.
(b)Heat test is the correct option.
Reason-Qualitative analysis is the analysis where the amount or mass of the compound or solute does not decides the product formed or changed occur.
Heat tests are not type of qualitative analysis because the amount of heat released or absorbed by the substance depends on the moles of mass of the substance used.
Hence (b) is correct option.
Thanks and regards!

Qualitative analysis can determine the metal cations that are present in a sample based on their solubility characteristics.
Qualitative Analysis of Metal Cations Qualitative analysis can determine the metal cations that are present in a sample based on their solubility characteristics. One such scheme is shown in the flow diagram. Some ions that are soluble in all of the test solutions can still be identified based on flame tests. Certain ions impart characteristic color to the flame.Part AA solution contains some or all of the ions Cu2+, Al3+, K+, Ca2+, Ba2+, Pb2+, and NH4+. The following tests were performed, in...

Regarding the qualitative analysis experiment which of the following statements is false? Ellagic acid decolorizes Br_2/CH_2Cl_2 and forms a colorful complex with aqueous FeCl_3. Pulegone reacts positively with 2,4-DNP and Br_2/CH_2Cl_2 reagents. Isoamyl alcohol gives positive NaI/acetone and negative AgNO_3/EtOH tests. Tyrosol reacts positively with Br_2/CH_2Cl_2, and Jones reagents. Umbelliferone gives a positive test with B Br_2/CH_2Cl_2 and negative with 2,4-DNP. Furfural gives positive 2,4-DNP, and Tollen's tests. Which one of the following reagents is not corrosive?
