The Fehling test is used to detect glucose, aldehydes and ketones. Benedict's test is used to determine the presence of reducing sugars such as fructose, glucose, maltose and lactose. It is also used to test for the presence of glucose in urine. The two tests are not exactly the same.

Why is the Glucose Oxidase test a more specific test for urinary glucose that Benedict's test?
the tests are more simple and sensitive than Benedict's tes
Why is heat applied in Benedict's test and not alcohol emulsion test?
They're two totally different tests. The alcohol emulsion test is for fat, and it works because water and oil don't mix. The reaction in the Benedict's test requires heat to work.
What is the difference between designer babies and test tube babies?
They are the same things
What is Benedict test for?
You must take the testing object, then add Benedict's solution in a test tube. Then in a boiling beaker of water, place the test tube in. Let it sit there and see if there is any color change or precipitated materials.
What does Benedict's reagent detect?
Benedict's reagent is used as a test for the presence of all monosaccharides, and generally also reducing sugars. These include glucose, galactose, mannose, lactose and maltose. Even more generally, Benedict's test will detect the presence of aldehydes (except aromatic ones), and alpha-hydroxy-ketones, including those that occur in certain ketoses. - wikipedia
What is the difference between Benedict's solution and fehling's solution?
Fehling's test uses tartaric acid, and Benedict's test uses citric acid
What regent is used to test for starch?
Fehling A and B Benedict solution
Are substances considered reducing in fehling's test also the substances reducing in Benedict's test?
yes.
Which is more sensitive the benedict's or fehling's test?
Fehling's test is more sensitive than Benedict's test. It is a more reliable method for detecting reducing sugars, such as glucose and fructose, due to its two separate solutions that are mixed before use, allowing for more accurate results compared to the single solution used in Benedict's test.
What is the difference between iodine solution and Benedict's solution?
Benedict's solution is used to test for simple sugars and iodine is used to test for starches.
What is the function of Fehling's test?
Fehling's test is used to differentiate between aldehyde and ketones group. An aldehyde group will react with Fehling's reagent to give cuprous oxide resulting in a red precipitate. A Ketone group will not react with Fehling's reagent.
What tests are used to test for the presence of starch and glucose?
for the starch iodine test is performed in which the starch reacts with iodine to produce dark blue colour which confirms the presence of starch. for glucose benedict's and fehling's test is performed. benedict's test: 1 ml sample is mixed with 1 ml of benedicts solution and the heated upto boiling if the colur changes to brick red then it confirms the presence of glucose fehling's test: similarly 1 ml fehling's solution I & fehling's solution II each in taken together and to it 1 ml of the sample is takenon then heated uptill boiling. if the colour changes to brick red the it confirms the presence of glucose.
Does formalin give positive Fehling's solution test?
Formalin gives a positive Fehling's solution test.
What is a positive test for carbohydrates?
These are the carbohydrate tests that would give a positive result on maltose: 1.Molisch test 2. Fehling's Test 3. Benedict's Test 4. Nylander's Test 5. Tollen's Test 6. Seliwanoff's Test 7. Barfoed's Test
Is fehling test positive for gluconic acid?
No. Fehling's test is positive for glucose which forms gluconic acid as the product.
Does formic acid fehling's test?
No, Fehling's Test will have no reaction with Formic Acid HCOOH + 2CuSO4 + 4NaOh ---> no Reaction
Why starch does not give with fehling test?
Starch doesnot give positive result for Fehling's test as it does not have a free hemiacetal group
