During conversion of starch into sugar, acids are added to increase the speed of the reaction, which type of catalyst is acid?
Answers
Answer:
Acid hydrolysis can be used for the preparation of monosaccharide. Hydrochloric acid, sulfuric acid, trifluoroacetic acid, formic acid, and nitric acid are commonly used in acid hydrolysis. Compared with other methods, acid hydrolysis results in a higher sugar yield and good reproducibility. However, acid hydrolysis will produce large amounts of degradation products from monosaccharides such as furfural generated from pentose and hydroxymethylfurfural produced from hexose (which further degrades into formic acid and levulinic acid). Therefore, the type of acid, pH, reaction temperature, and reaction time should be considered carefully in acid hydrolysis
Answer:
the modification of the rate of a chemical reaction, usually an acceleration, by addition of a substance not consumed during the reaction. ... Therefore, a catalyst does not affect the position of equilibrium of a chemical reaction; ... These included the enhanced conversion of starch to sugar by acids
