To identify substance J, we need to synthesize the observations and inferences from the provided table: 1. Preliminary Test (top of page): "A persistent golden yellow colour" indicates the Presence of Sodium (Na) in the sample. 2. Test (i) - Dissolving J in water and testing with litmus: Observation: "Turns red litmus paper blue and has no effect on blue litmus paper." Inference: "Solution is alkaline. Substance is an amide or salt of a weak acid and a strong base which undergoes hydrolysis." This confirms J forms an alkaline solution. 3. Test (iii) - Adding dilute hydrochloric acid to the solution of J: *
