WebFouchet’s reagent used in Fouchet’s test comes under oxidizing reagent or test. Barium chloride precipitates the sulphate radicals present in urine to form precipitate of barium sulphate. If bile pigments are present in urine, they adhere to these molecules. Ferric chloride present in Fouchet’s reagent then oxidises yellow bilirubin, in ... WebMolisch’s Test Procedure. 2-3 drops of Molisch’s reagent must be added to a small amount of the analyte in a test tube and mixed well. Now, a few drops of concentrated sulphuric acid must be added drop-wise along the walls of the test tube to facilitate the formation of a layer and avoid mixing.

http://api.3m.com/rothera+test+for+ketone+bodies WebTheir excretion in urine is very low and undetectable by routine urine tests (Rothera's test). When the rate of synthesis of ketone bodies exceeds the rate of utilization, their concentration in blood increases; this is known as ketonemia. This is followed by ketonuria – excretion of ketone bodies in urine. WebNoneof the tests gave a colour with 3-hydroxybutyric acid, and the contribution of the acetone towards the colour development of the Rothera and tablet tests was probably negligible, because Nash et al. (1954) reported that Rothera's test gave only a trace reaction with 25 mg./100 ml. of acetone in normal urine. The funny mugs for aunt and uncle
