3,5-dinitrosalicyclic acid is an aromatic compound that react with reducing sugar to form 3-amino-5-nitrosalicyclic acid which absorbs light strongly at 540nm.
DNSA reagent appears yellow due to ts nitro gp.(chromophore) an alkaline solution of Dnsa is boiled with the reducing sugar to bbe estimated Orange brown coloration result which is read colorimetrically.
The principle of the aluminium chloride method involves using aluminium chloride as a catalyst to promote the Friedel-Crafts acylation or alkylation reaction. This method is commonly used in organic chemistry to introduce new functional groups onto aromatic compounds. The aluminium chloride coordinates with the electrophile and enhances its reactivity towards the aromatic ring.
Colorimetric method where blood is mixed with solution containing potassium ferricyanide and potassium cyanide. Potassium ferricyanide oxidizes iron to form methemoglobin and potassium cyanide then combines with methemoglobin to form cyanmethemoglobin.
The principle of agar diffusion method is based on the diffusion of an antimicrobial agent from a sample into an agar medium containing a test organism. The size of the zone of inhibition that forms around the sample is used to determine the effectiveness of the antimicrobial agent against the test organism.
Biamperometric titration is a method of quantitative analysis that involves the determination of analyte concentration by measuring the current produced when two working electrodes are polarized at fixed potentials. The principle is based on the measurement of the difference in current between the two electrodes, which is proportional to the concentration of the analyte being titrated. This method is useful for titrations that involve redox reactions.
DNSA reagent appears yellow due to ts nitro gp.(chromophore) an alkaline solution of Dnsa is boiled with the reducing sugar to bbe estimated Orange brown coloration result which is read colorimetrically.
by comparing the colours or the amount of precipitate
It detects reducing sugars. DNSA -----> 3-A, 5-N SA
3, 5- dinitrosalicylic acid is the full form of dnsa.
They are both the same. displacement method is another name for Archimedes' principle
When a sugar molecule reacts with 3,5-dinitrosalicylic acid (DNSA), the sugar is oxidized to form a colored product. This color change is used to detect the presence of reducing sugars, such as glucose, in various chemical tests, including the DNS method for quantifying sugar concentrations.
the principle of this test are used the method of a qualitative test for the detection of nematode and cestode eggs and coccidia oocysts in the faeces.
