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. 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.
