250 mL of water sample was collected from a river and sent to a laboratory to determine the concentration of the total suspended solid. In the laboratory, 5 mL of the water sample was transferred to a 100 mL volumetric flask before diluted with distilled water to 100 mL. After that, 50 mL of the diluted water sample was transferred to a funnel containing a glass fiber filter and attached to a glass flask with the sidearm connected to a operating vacuum pump. Transferred diluted water sample was left drained through the glass filter before glass fiber was transferred to an oven to heat at 105 oC under a constant weight of 0.2654 g was obtained. If the initial weight of the glass fiber filter is 0.2431 g. Calculate the amount of the suspended solid in mg unit contained in the 250 mL collected water sample.

Human saliva contains the enzyme α-amylase which hydrolyzes polysaccharide acetal linkages. A soda cracker (containing starch) was carefully ground; the crumbs were distributed evenly between two test tubes. The first test tube contained only water, while the second contained a 1% solution of α-amylase. Both mixtures were heated to 35°C for 10 minutes and filtered. The filtrates were tested with iodine solution and Benedict’s solution. Use the following results to answer the questions below. Mixture Iodine test Benedict’s Test cracker in water dark blue blue cracker in water and α-amylase red red-orange precipitate a. Was the starch from the cracker/water mixture hydrolyzed? Was the starch from the cracker in the 1% α-amylase solution hydrolyzed? b. Which cracker contained reducing sugars?
