Can reagent bromthymol blue or phenolphthalein could be considered to be an acid indicator?
Phenolphthalein is typically used as a base indicator as it changes color in the presence of bases. Bromthymol blue can be used as both an acid and a base indicator, with different color changes for each.
What indicator should be used to see maltose?
To detect maltose, you can use the Benedict's test. Benedict's reagent will change from blue to red or yellow in the presence of reducing sugars like maltose.
What is the difference between fehling's solution and tollens reagent?
Fehling's solution is used to test for the presence of reducing sugars, while Tollens reagent is used to test for the presence of aldehydes. Fehling's solution contains cupric ions, while Tollens reagent contains silver ions. When a reducing sugar reacts with Fehling's solution, a brick-red precipitate forms, while with Tollens reagent, silver ions are reduced to form a silver mirror on the test tube.
Why is a small amount of indicator added during titration?
An indicator shows when we have added just enough of the second reagent to react with the first. If you mean why do we add only a small amount of indicator, it is to keep the answer accurate. Some of the reagent is used changing the indicator so the answer is always slightly bigger than perfection, and the more indicator you add, the larger the error.
What is Patton and reeder's reagent?
Patton and Reeder's reagent is a stain used in histology for the identification of lipids. It is a mixture of osmium tetroxide and potassium dichromate. When tissues are stained with Patton and Reeder's reagent, lipids appear black or dark brown in color under a microscope.
