Answer 1

here is the answers, please see the images

to yellow precipitate is obtained reducing Sugers caro no blue, then Bendie's test is positive for Reducing sugans.. of the after test Red, green and yellow precipitare then Reducing sugars present. to solution pemain clearo no blue, then edheng is not present . Seliwanots test positive for ketose give red coloro formed rapidly. godine test Positive toro polysaccharides. purple block - positive & Yellow-orange- negative Fermentation test The carbohydroute termentation test is used to determine wherether or not a bacteria can utilize a certain carbohydrate. gt tests for the presence of acid and for gus prooduced from the fermentation of a carbohydrate. Lactose does not prooduce bubles in this test. Unknown A Bendits test: Bluish color Negative, hon reducing sugar Seliwanoth's test: Red, positive, centain keto henose, Fermentaitim test, positive, not Lactose, godine test no color charge, not polysacharide. So It must be suchose, which is disucchunide, non reducing sugar, . (ove Bentits test) fi contin keto herose (ve Seliwunoppis test A = Suchose (others are not fulfill this criteria mentim ahore

@ Bendicts test, positive, Seliwanotas tert, Ove, godine test, no coloro reducing sugar > Not Ketcherase not polysacharides. change Fermentation text ve not Lactose so it must be glucose which is aldose and be ducing sugar. ez Glucose Benedict's teet: Iodine test Pupple/black = positive Indicates, it must be polysaccharide and definately stapch. ( others one, negative. for this tes E3 Stareh ove in Bendict' stest - Reducing sugar, Seliwanoft's test ove contain ketohenose So it must be Frouctose, which is ketose of beducing sugans. G= Frouctose K) Ave Bendict's test, reducing sugar. Seliwano ft' stest: Ove, not ketoherode godine test :ove, not polysachharides- Fermentation test : eve, for Lactose. So k must be Lactose. Among all of h compounds only one is negative in termentation test. Centuin .
