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.
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.
yes.
A positive result for the Fehling's test indicates the presence of a reducing sugar such as glucose or fructose in the solution. This is shown by the formation of a brick-red precipitate when the Fehling's reagent is added and heated with the sugar solution.
Sucrose would not give a positive test with Fehling's reagent after hydrolysis because sucrose is a non-reducing sugar. During hydrolysis, sucrose is broken down into its monosaccharide components (glucose and fructose), which are reducing sugars and can react with Fehling's reagent to give a positive test for reducing sugars.
No, ALT (alanine aminotransferase) is not typically used to test for kidney function. It is an enzyme primarily found in the liver and is commonly used to assess liver health and function. Tests such as creatinine or blood urea nitrogen (BUN) are usually used to evaluate kidney function.
ulo nyo!!
Fehling test is used for reducing sugars.
I think you are referring to the test using Fehlings solution. Fehlings solution oxidises aldehydes and ketones and formic acid and is in turn reduced. The red precipitate is the copper(I) oxide formed by reduction of the copper(II) complex found in Fehlings solution. Acetic acid is not readily oxidised and so there is no precipitate. See link for more information on what the complex is in Fehlings solution and how it is prepared.

"y = f(x) is a function if it passes the vertical line test. It is a 1-1 function if it passes both the vertical line test and the horizontal line test. " - In order to be a one-to-one function, it first has to BE a function and pass the vertical line test. For example, a relation on a graph like a circle that does not pass the vertical line test is not function nor one-to-one.

Horizonatal line test is a test use to determine if a function is one-to-one. If a horizontal line intersects a function's graph more than once, then the function is not one-to-one. A one-to-one function is a function where every element of the range correspons to exactly one element of the domain. Vertical line test is a test used to determine if a function is a function or relation. If you can put a vertical line through graph and it only hits the graph once, then it is a function. If it hits more than once, then it is a relation.
false!
Fehling's A solution is blue in color due to the presence of copper sulfate.
