A reagent is a substance consumed during a chemical reaction to produce a specific product, while a catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. In other words, reagents participate in the reaction, while catalysts facilitate the reaction without being altered themselves.

Why is ferric chloride only used in catalytic amounts?
Ferric chloride is used in catalytic amounts because it can regenerate during the reaction, making it a catalyst rather than a reagent. Using it in small quantities is cost-effective and minimizes waste disposal issues associated with excess reagent.
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.
How do you tell the difference between glucose and maltose using benedicts reagent?
Benedict's reagent can be used to differentiate glucose and maltose based on their reducing sugar properties. Glucose is a monosaccharide and will readily reduce Benedict's reagent to form a brick-red precipitate, indicating a positive test. Maltose, being a disaccharide composed of two glucose units, will also react with Benedict's reagent but may produce a less intense color change compared to glucose due to its structure.
What is tollen's reagent and baeyer's reagent?
Tollen's reagent is a test used to detect the presence of aldehydes, as it produces a silver mirror when it reacts with aldehydes, but not with ketones or other compounds. Baeyer's reagent is a solution of potassium permanganate (KMnO4) used to oxidize and distinguish between primary and secondary alcohols. Primary alcohols are oxidized by Baeyer's reagent to form carboxylic acids, while secondary alcohols are oxidized to form ketones.
What is the purity difference between hydrogen peroxide AR grade and hydrogen peroxide LR grade?
Hydrogen peroxide AR (Analytical Reagent) grade is of higher purity compared to LR (Laboratory Reagent) grade. AR grade typically has a purity of 95-97%, while LR grade has a purity of around 70%, making AR grade more suitable for analytical and research applications where higher purity is required.
What is the difference between a homogeneous catalyst and a heterogeneous catalyst?
The difference between a homogeneous and a heterogeneous catalyst is that in a heterogeneous catalyst, it is in a different phase from the reactants. However, in a homogeneous catalyst, it is in the same phase as the reactants.
What is the main difference between a heterogeneous catalyst and a homogeneous catalyst?
The heterogeneous catalyst is not mixed with the reactants.
What is the Raney Ni catalyst?
RANEY Nickel is a reagent and a catalyst in organic chemistry,,,and it is use in hydrogenolysis of glycerol.
What is a term for catalyst?
one name for a catalyst is... to be onis i have no idea myself xxx
What is the difference between an inhibitor and catalyst?
Catalyst speeds up reactions, and inhibitors are used to slow down reactions.
What is the difference between enzymes and catalyst?
There is no difference. An enzyme is a natural catalyst. Catalysts speed up the rate of reaction without being used up itself.
Why only ethers are used as a catalyst in grignard reagent reactions?
Ethers are used as solvent in Grignard reaction and not as catalyst. This is because if we use other solvents which have acidic hydrogen, Grignard reagent will decompose and the Grignard reaction will not proceed further.
What is the difference between Benedict's Reagent and Biuret Reagent?
Benedicts reagent is used to check reducing sugars , it need hat to work and gives red color when positive ,. While biuret reagent is for proteins .there is no need to use heat and gives purple , violet color when positive ..
What is the difference between a catalyst and an inhibitor?
Catalyst: a substance which promote and help a chemical reaction. Inhibitor: a substance which greatly reduces the rate of a chemical reaction.
The difference between catalyst and inhibitor?
A catalyst lower the activation energy (speeds up the reaction) while an inhibitor increases the activation energy (slows it down).
What is the mechanism of reaction between Wagner's reagent and alkaloids?
what is the reaction mechanism between wagner's reagent and alkaloids
What is the difference of dropping bottle and reagent bottle?
The reagent bottle is not used for dropping, having only a common stopper.
