potato juice if mixed with benedict's reagent will give a brick-red precipitate.
because know one cares
It is a heavy glass bottle (unlikely to break or react with the reagent chemicals) used to store moderate amounts of laboratory chemicals (reagents)
Does not react. Because Tollens' reagent only works with aldehydes. Butanone is methyl ethyl ketone (MEK).
Fructose and glucose are joined by their glycosidic bond in such a way as to prevent the glucose isomerizing to aldehyde, or the fructose to alpha-hydroxy-ketone form. This stops it reacting to Benidict's reagent. However sucrose indirectly produces a positive result with Benedict's reagent if heated with dilute hydrochloric acid prior to the test, although after this treatment it is no longer sucrose. ;-)
It should react to this reagent. However it must be HEATED before it will react.This is due to the fact that when Ninhydrin is heated it stabilizes and the reacts with the -NH2 groups on the amino acid.
No, they must be heated in order to react
The biuret reagent should not react with a single amino acid. The reagent reacts when there is a peptide bond linking amino acids together. If you are seeing the biuret reagent react in the presence of a single amino acid, then there must be some amino acids that are still linked together.
because
yes!!
usually it will be copper sulfate as a limiting reagent
vanillin violently reacts with Bromine in carbon tetrachloride,tollens reagent and aqueous NaOH
A "reagent" or "reactant".
Yes, it results in a Grignard reagent.
potato juice if mixed with benedict's reagent will give a brick-red precipitate.
No, it changes lavenderish when protein is present.
Tollens' reagent is used to determine whether a carbonyl containing compound is an aldehyde or a ketone. Acetone is a ketone so it will not readily react with Tollens' reagent.
