What happens when you heat NaHC03 in a test tube?
It partially decomposes to Na2CO3, CO2 and H2O according to: 2NaHCO3 --> Na2CO3 + CO2 + H2O
Do eggs test positive in benedicts test?
Yes, eggs can test positive in the Benedict's test because they contain glucose, which is a reducing sugar that reacts with the reagent in the test to form a colored precipitate.
Would sucrose test positive or negative with benedicts reagent?
No, surcose is a disaccharide without a hemiacetal group
Why Na2Co3 extract is not used for carbonate test?
Na2CO3 extract is not used for carbonate test because it is a carbonate compound itself (sodium carbonate). Using it in the test would not provide a valid result, as it would already contain carbonate ions. To test for carbonate ions, a substance that does not already contain carbonate, such as hydrochloric acid, is used.
Why is sodium carbonate added to solution before Benedicts test is performed?
Sodium carbonate is added to increase the pH of the solution.
What are the Benedicts test results for Gatorade?
penis
What is the test for sugar using Benedicts solution?
prosrdure of benidect solution test
Why Na2CO3 is added to solution before Benedicts test is performed?
Na2CO3 is added to the solution before the Benedict's test to create an alkaline environment, which helps to stabilize the blue copper (II) ions in the Benedict's reagent. This stabilization is important for the detection of reducing sugars, as the copper (II) ions must be reduced to form a red precipitate in the presence of reducing sugars.
Which is more sensitive test fehlings test or Benedicts test?
Benedict's test is more sensitive than Fehling's test for detecting reducing sugars in a sample. Benedict's reagent has a lower detection threshold and is known to give more accurate results compared to Fehling's reagent.
Why should you add 8 drops of urine in the Benedict test?
why should you add 8 drops of urine in the Benedicts test
What does a negative Benedicts test indicate?
A negative Benedict's test would indicate that there isn't any presence of reducing sugars in that particular substance.
