Sample K + Benedict’s solution Solution remains blue Larutan kekal biru Sample M + Benedict’s solution Solution remains blue Larutan kekal biru Sample J + Benedict’s solution Red orange precipitate Mendakan merah bata Sample L + Benedict’s solution Red orange precipitate Mendakan merah bata Based on the observation, (a) State one characteristic of food sample J,K,L and M J: K: L: M: Possible answers Orange red precipitate formed Terbentuk mendakan merah bata. Solution remains blue Larutan kekal biru. observation Please answer
7. (b) Classify food sample J,K,L and M into two groups based on their common characteristic . Glucose is present Terdapat Glukosa No Glucose is present after tested with Benedict’s solution. No Orange red precipitate formed Tiada mendakan merah bata. Solution not kept blue Larutan tidak kekal biru. Orange red precipitate formed Terbentuk mendakan merah bata. Solution remains blue Larutan kekal biru. J: K: L: M: J: K: L: M: Orange red precipitate formed Terbentuk mendakan merah bata Orange red precipitate formed Terbentuk Mendakan merah bata. Solution remains blue Larutan kekal biru Solution remains blue . Larutan kekal biru. carry foward correct answers Choose only one characteristic ! Common characteristic Alphabat Huruf
8. Sample J + Benedict’s solution Red orange precipitate Albumin + Benedict’s solution Test tube N Test tube P ( c ) i. State one inference based on the observation in the test tube N Nyatakan satu inferens berdasarkan pemerhatian pada tabung uji N. .................................................................................................................. ……………………………………………………………………………………… ii. Predict the observation in the test tube P. Ramalkan pemerhatian pada tabung uji P ................................................................................................................................ iii. State the relationship between changes of colour of Benedict’s solution and the presence of food. Nyatakan perhubungan antara perubahan warna larutan Benedict dengan kehadiran makanan. ………………………………………………………………………………………………… . ……………………………………………………………………………………… Red orange precipitate formed Mendakan merah bata terbentuk Because kerana Sample J contains glucose / sampel J mengandungi glukosa Solution remains blue Larutan kekal biru. If Benedict solution change to red orange, Jika larutan Benedict bertukar menjadi merah bata glucose is present , Terdapat glukosa.
